PROFESSIONAL EXPERIENCE

University of Illinois at Urbana-Champaign, Urbana-Champaign, IL

Research Assistant Aug 2014 – Present

Study the zinc cation and oxygen anion co-injection behaviors in ZnO (0001) single crystal

-Built up a UHV system and solved the technical problems in the system for conducting the experiments

-Applied unique clean surface condition in ZnO to manipulate the zinc cation injection

-Studied the kinetics of Zni and Oi injection via surface pathways into ZnO (0001) single crystal with UHV-based isotopic exchange experiment and Secondary Ion Mass Spectrometry (SIMS), which gave the experimental evidences that Zni diffused much faster than Oi, and existence of Zni could slow the diffusion of Oi

Study the native defect behaviors in ZnO (0001) after injection of Zinc and Oxygen by Photoluminescence

-Set up the photoluminescence measurement system

-Calibrated the photoluminescence system to extract the consistent data

-Investigated the cation behaviors incorporated with SIMS, and gave out the experimental evidences that sole VO or Oi couldn’t contribute to the green emission of ZnO
