PROFESSIONAL EXPERIENCE

UCLA (1997 – present):
Materials Science and Engineering, UCLA, ( July 2002-present), Professor.
Materials Science and Engineering, UCLA, ( July 1998-June 2002), Associate Professor.
Materials Science and Engineering, UCLA, ( Jan. 1997-June, 1998), Assistant Professor.

Since 1997 I joined UCLA, we have graduated 12 PhD and 3 MS degrees; published 110+ refereed papers, presented 70+ invited talks, and filed/issued 37 patents. Currently, we have a group of 17 PhD students, 6 postdocs and 4 visiting scholars; and the annual research grants are in the range of 1.85 million dollars per year. Our research can be found at this weblink: http://www.seas.ucla.edu/yylabs.

The Yang laboratory focuses on five major areas of organic electronic and optoelectronic devices:
  1. organic/polymeric nonvolatile memory devices; by combing organic semiconductor and nano-particles, the Yang group has been the leading group in the research of solid state organic nonvolatile memory devices. Our group has discovered the nano-particle induced electrical bistable effect, understand the mechanism, and subsequently applied to other type of organic memory devices. Technology transfer: Silinna Inc. in Australia
  2. organic photonic materials and devices (LEDs); our group is one of the leading groups in polymer LEDs. We demonstrated inkjet printing of PLED in 1997, solution PLED in 1998, laminated PLED in 2000, and recently we have demonstrated a very high efficiency PLED (36cd/Amp) through interface engineering. Technology transfer: Canon Inc. (Japan)
  3. organic/polymeric transistors: our transistor goes vertically. By integrating the gate electrode in the bottom, and a source electrode in the nano-scale thickness, we have successfully demonstrated vertical organic transistor. Device with very high performance (4A/cm2 current density and in 4 volts of S-D voltage) has been demonstrated. Technology transfer: ORFID Corp., Los Angeles, California.
  4. organic/polymeric photovoltaic devices. Polymer photovoltaice device is another type of polymer photonic device we are working on. We emphasize on novel polymers, unique device architecture, fundamental understanding of device physics, and interface formation. Our device has reached efficiency of closed to 5% efficiency, this is one of the highest records in the polymer solar cell technology. Technology transfer: Solarmer Energy Inc., Los Angeles, California.
  5. graphene: This is the latest research field that we entered. By a unique processing method, we have created by far the largest graphene sheets. Our paper is current under review by journal of Nature Nanotechnology. This is a joint research with Prof. Richard Kaner of the Chemistry Department, UCLA.
