MAJOR ACCOMPLISHMENTS

Contributed to the advancement of science and technology with world-class, trend-setting research in the fields of electronic, magnetic, optical, superconducting, electronic packaging, and MEMS materials and devices, and nano-bio materials.  The pioneering and leadership nature of my work is evident by a large number of Science Citation Index (~11,000), US Patents (~200 issued or pending), publications (~300), and invited or keynote talks (~120) at major professional societies.

 

1.      Discovered (and named) Colossal Magneto-Resistance (CMR) phenomenon in perovskite La-Ca-Mn-O thin films in 1994.  My publications in Science [with ~3000 citations, 4th highest cited paper in the physical science field during the past decade], JAP, APL and the invited talk at the Magnetism and Magnetic Materials Conference touched upon the imagination of many people, and immensely stimulated world-wide research in this field.  Very large change in electrical resistivity by more than four orders of magnitude was obtained.  The fact that electrical resistivity of a material can be manipulated by applied field to change by orders of magnitude (and the corresponding variability in Ohm’s law relationship) could be useful, if the CMR materials are properly developed, for a variety of electrical and magnetic devices including ultra-high-density, hard-disk recording heads, future spintronics devices.

 

2.      Developed ductile permanent magnet alloys of Fe-Cr-Co (chromindur) based on spinodal decomposition for reliable and miniaturized telephone receiver applications.  As many as 10 million cup-shaped magnets per year have been manufactured and used in-high quality AT&T telephones since early 1980s, with a total economic impact (savings) of over $200M (equilvalent to ~$ 1 billion in today’s dollar value).

 

3.      In response to the worldwide cobalt supply crisis in early 1980’s, I developed a series of cobalt-free, square-loop semi-hard magnet materials including Fe-20Ni-4Mo and Fe-8Mn alloys.  They are now widely used in billions/year of anti-theft security tags   for electronic surveillance in various retail stores.

 

4.      Developed voltage-pulse-generating magnetic wires (remotely actuate-able by external magnetic field) for possible implantation for functional electrical stimulations of neurons, accelerated bone healing, remote pacemakers, and other biomedical applications.

 

5.      Designed new, optically transparent (~98%) yet electrically conductive polymer-metal particle composite structure with z-direction-only anisotropic conductivity using     vertically alignment of chain of ferromagnetic metal particles (Published in Science). The structure can be useful for touch-sensitive screens and other optical applications. The anisotropic conductivity can be useful for solderless electronic interconnections, non-invasive circuit tests for commercial high-frequency IC products, and potentially for tactile sensor skins for robotic or bio applications.

 

6.      Designed and demonstrated magnetically tunable optical fiber grating device which allows latchable reconfiguration of Bragg filtering wavelength for potential wavelength division multiplxed (WDM) optical telecom systems.

 

7.      Contributed to Lucent’s exciting optical MEMS program (involving 100+ scientists) with valuable work of enabling the stability and performance of light-reflecting mirrors.  World’s largest and fastest telecommunication optical switching systems using the free-space optical MEMS has been demonstrated by Lucent  at the Yr 2001 OFC Conference (Optical Fiber Conference), the capacity of which would allow the switching of today’s  whole day internet traffic in less than a second if needed.

 

8.      Demonstrated, for the first time, and within a month after the announcement of the 90K superconductor, the feasibility of high Tc superconductor(HTSC) wires from the mechanically brittle ceramic superconductors was demonstrated through the study of diffusional interactions between various metals and the reactive high Tc  materials, and through fabrication of silver clad superconductor wires.  This silver-clad approach was widely used by many researchers and industries in US, Japan, and Europe (IGC, American Superconductors, Sumitomo, etc.) for fabrication of Bi-Sr-Ca-Cu-O and Tl-Ba-Ca-Cu-O based high Tc superconductor wires and prototype/demonstration superconducting magnets with ~2 Tesla generated field.  I have been awarded several broad patents on HTSC wires covering cuprate superconductors.

 

9.      Pioneered (and named) the Melt-Textured-Growth processing for HTSC and demonstrated for the first time that the grain boundary weak link problem in bulk high Tc superconductors can be overcome and high critical current density can be obtained.  The principle of partial melt processing for grain alignment is now employed by world-wide researchers in order to achieve high critical currents (Jc) in Y-Ba-Cu-O, Bi-Sr-Ca-Cu-O, and Tl-Ba-Ca-Cu-O bulk superconductors and wires, and led to commercial applications such as efficient and sharp, telecommunication frequency filters for Bell Atlantic, Ameritech, and other companies.

     For the leadership quality R&D in the superconductor field I received the “1990 Person of the Year” award from Superconductor Week which selected one person with greatest contributions per year from more than 1200 physicists, chemists materials scientists, and electrical engineers then actively engaged in high Tc research.  I was also selected as one of the Top Ten Innovative Scientists in U.S. (in the collective field of biology, chemistry, physics and electrical engineering) by Business Week magazine (August 14, 1989), and was featured in the centerfold photograph in Life magazine (September 1987).

 

10.  Initiated the trend and displayed leadership in advocating and promoting R&D in early 1990’s on the environmentally safe electronic solders, especially Lead-Free Solders.  (Europe and Japan are leading the effort to ban the use of lead-containing solders in coming years in electronic/consumer devices, with “cradle-to-grave-responsibility” type environment policy legislations for manufacturers and imported products). I organized the first eight “Lead-Free Solder” symposia for the metallurgical society meetings (1993-1997), and firmly established TMS as the leading society for discussing and advancing Pb-free solder science and technology.     Edited a Special Topics Series on lead-free solders for JOM (The Journal of the Minerals, Metals and Materials, July 1993).  Developed a series of new lead-free solder alloys with superior  properties such as Universal Solders, using unique alloy design approaches.

 

11.  Discovered a new diamond processing technique using diffusional thinning, polishing and shaping of diamond by molten rare earth metals.  While diamond has the highest thermal conductivity of all known materials and provides exciting thermal management possibilities in modern electronic and optoelectronic designs, it is the hardest material known to mankind and the conventional mechanical polishing and shaping (usually against diamond) is time-consuming and costly, sometimes accounting for as much as one-half of CVD diamond cost.  The new technique is fast and, unlike the conventional method, allows simultaneous processing of  thousands of diamond pieces or wafers.  The significance of this work was recognized by  publications in the journal Nature, etc., and its coverage by BBC radio in 1994 Science-in-Action program. 

 

12.  Pioneered the desirable iron-clad superconductor wire structure for the newly discovered MgB2 superconductors, and demonstrated for the first time that the volatility problem associated with the presence of magnesium can be overcome and promising superconductor characteristics and configurations can be obtained. This work was published in Nature in May, 2001, and covered by New York Times, Financial Times,  and various news media. 

 

13.  Demonstrated new, on-chip MEMS vacuum microtriode device by combining the world of nano with that of MEMS. Carbon nanotube cold cathode was utilized  to construct a miniature triode field emission device for microwave power amplifier applications.  The pioneering nature of this work was recognized and covered by news media and respectable science magazines/journals including Physics Today (July 2002, www.physicstoday.org ), MRS News (July 23, 2002), Nature (Materials Update, May 2002, www.nature.com/Physics ).

 

14.  Demonstrated for the first time that sharply bent (zig-zag or 90o bent) carbon nanotubes can be fabricated using inhomogeneous electric field distribution during CVD growth.(Published in Nano Letters 2004)  As compared to the generally straight nanowires, such bent nanotubes have far more utility, e.g., as route-able in-plane circuit nanoconductors, zig-zag nanotubes for stress-accomodating vertical interconnects, bent-tip AFM nanoprobes for sidewall metrology, and other potential applications such as nanosolenoids. Ultra-sharp AFM probe tips as small as 1 nm tip diameter has also been demonstrated for accurate imaging of nanostructures and devices, and ultra-soft-caltilevered AFM probes (~1/000 elastic modulus of standard AFM probe) with high aspect ration carbon nanotube tips have been demonstrated for imaging of soft matters such as living cells, soft polymers, and delicate nanodevices. 

 

15.  Discovered that vertically aligned and well-adhered TiO2 nanotubes on Ti implant metal surface significantly increases the formation of hydroxyapatite and bone growth.  It is demonstrated that the kinetics of osteoblast cell adhesion/growth is accelerated by 300-400% on the nanoscale, topologically configured surface of the nanotubes (published in J. Biomed. Mater. Res. 2006), and the mobility of endothelial cells are much enhanced (published in Nano Lett. 2008). Also discovered that the stem cell (hMSC) differentiation can be dictated solely by TiO2 nanotube geometry so that either cell proliferation without differentiation or preferential differentiation into osteogenic lineage can be accomplished without using chemical inducing agents (published in PNAS, 2009).

 

16.  Discovered novel electronic switching behavior and logic in CVD synthesized carbon

      nanotube Y-junctions.(Nature Materials, 2005).  This is the first time that such an

      abrupt electrical switching behavior from “on” to “off” state has been achieved in

      CNT Y-junctions. Prior to this work, only a diode like behavior was observed.  This

      ready-made, three-way, nano-sized transistor device represents an entirely new class

      of nanoelectronic architecture and functionality, extending well beyond conventional

      field effect transistor technologies, making the overall nanotube based nanoelectronic

      architecture more complete and feasible.

 

17.  Contributed to the design of dual-elastic-modulus composite materials, and discovery of strongly nonlinear acoustic materials with exciting “energy trapping and shock wave disintegration” characteristics (Phys. Rev. Lett., 2006).   A shock wave impulse can be made to be confined at the soft-hard modulus interface of chain of spheres, which then allows the trapped shock energy to be slowly released in the form of weak, separated pulses over an extended period of time. Such control of acoustic waves can be useful for powerful shock mitigation, sound absorption, drastic compression/decomposition/focusing of acoustic signals for signal scrambling, and more accurate acoustic therapeutics for brain tumors and other medical disorders.
