Research Interests:

  • Expert in molecular beam epitaxy (MBE) of III-V/Arsenide compound semiconductors, 2D quantum wells, material design/epitaxy on GaAs and InP substrate.
  • Extensive practical experience in bulk single crystal growth, process development, and materials characterization (Raman scattering, X-ray diffraction, and transport measurement).
  • Problem solving in solid state physics by means of High Resolution TEM, scanning electron microscopy and focused ion beam.
  • Hands on experiences in micro/nano fabrication including SQUIDS, CVD, wet etching, optical lithography, familiar with clean-room environment and characterization techniques.
  • Strong skills in Matlab, Labview, C/C++, Visual Basic and data analysis, familiar with python and statistical methods.
  • Experience in directing the effort of complex projects and coordinating the efforts of an interdisciplinary engineering team.

Biography:

Education: 

  • Ph.D. in Optics, Jilin University, China, 2001
  • M.S. in Optics, Jilin University, China, 1998

Research Experience:

  • 2005- present-   Researcher, University of Illinois at Urbana Champaign Urbana, IL, USA.
  • 1998-2004-   Graduate Research Assistant, Jilin University

Research focus: 

  • I am interested in studying fundamental properties of solid state systems, such as the correlated electron systems that have rich phase diagrams as a function of doping, including insulating, ferromagnetic metal, and antiferromagnetic ground states. 
  • I am using various optical techniques, including reflectance and light-scattering spectroscopies, to characterize the excitation spectra of these materials, and to elucidate the mechanisms driving the different phase transitions. 
  • I am also interested in synthesizing and characterizing several materials using flux and other crystal growth techniques and analyze their properties using various characterization methods.
