Our research seeks to address outstanding problems in semiconductor science and technology. To this end our group pursues investigations in the areas of photovoltaic materials, 2D semiconductors, and bandgap engineering of novel III-V and II-VI semiconductor materials. Our efforts combine both materials synthesis and characterization, applying advanced growth and processing methods in combination with a broad suite of materials analysis techniques.

Current Research Activities

  • Novel transparent conductive oxides (in collaboration with the Solar Energy Materials Research Group at LBNL)
  • Synthesis and characterization of novel III-V highly mismatched alloys
  • Optical properties of layered chalcogenides (e.g GaTe)
  • 2D materials synthesis on metal substrates

We are affiliated with the Department of Materials Science and Engineering at the University of California, Berkeley, and the Materials Science Division at Lawrence Berkeley National Laboratory.
