Graduate Research Assistant
Urbana-Champaign, Illinois Area
• Designed and grew semiconductor heterostructures using molecular beam epitaxy (MBE) growth for solar cells, lasers, and contact layers for projects funded by the Department of Energy (DOE) and National Science Foundation (NSF)• Achieved InAs virtual substrates with the lowest defect density in the world by over 2.5x through extensive characterization and defect analysis using scanning electron microscopy (SEM), atomic force microscopy(AFM), x-ray diffraction (XRD), and photoluminescence (PL)• Established a device fabrication procedure (photolithography, etching, metallization) in the cleanroom for semiconductor laser diodes along with electrical testing procedures (I-V and L-I-V) to successfully realize the first electrically-injected continuous wave laser in our lab at UIUC• Developed hardware and integrated software for mid-infrared photoluminescence and laser testing setups using electrical probe stations, optical test bench, and Python programming for automating testing and data collection for electronic device and materials characterization• Performed extensive data processing in MATLAB, Python, and Excel to analyze results and execute statistical data analysis for electronic device performance and material quality assessment• Developed effective communication skills through biweekly research presentations, collaborative meetings with other universities (Arizona State University, University of Texas at Austin, Yale University), and quarterly progress reports to the Department of Energy
