Current Job Openings

MBE Growth Postdoctoral Fellow

Job Duties:

• Prepare and load individual wafers into the crystal growth chamber and monitor controls:
  • Preparing and using chemicals for controlled etching of wafer substrates (a wafer is a thin slice of a semiconductor);
  • Monitoring the chemical etching process and effect on wafer substrates’ surface;
  • Optimizing the etching process to generate atomically flat, free of debris surfaces;
  • Loading wafer substrates into ultra-high-vacuum (UHV) MBE chamber.
• Perform molecular beam epitaxy of HgCdTe on various crystal substrates to include silicon and CdZnTe:
  • Fabricate semiconductor single crystalline thin films and complex layered structures by controlling and regulating the molecular fluxes, evaporating temperature, substrate temperature and pressures;
  • Test wafers using spectroscopic ellipsometry and analyze and prepare data in a readable format;
  • Testing single crystal semiconductors using in-situ and ex-situ characterization techniques such as Fourier-transfonn infrared spectroscopy (FTIR), reflection high-energy electron diffraction (RHEED), high-resolution x-ray diffraction (HRXRD), and scanning ellipsometry (SE) to assess their optical and structural properties;
  • Analyzing and interpreting the data, work with theoretical physicists and engineers to improve the quality of the grown wafers using feedback from testing.
• Characterize HgCdTe epitaxial films using Hall and photoconductive minority carrier lifetimes:
  • Testing single crystal semiconductors electrical properties using Van Der Pau w Hall measurements and photoconductive minority lifetime measurements.
• Experience with troubleshooting, improving, and modifying laboratory equipment, including MBE and ultra-high vacuum (UHV) equipment:
  • Troubleshooting and modifying the MBE chamber by controlling the UHV equipment and accessories.
• Experience with in-situ growth monitoring and diagnostic techniques.
• Work closely with theoretical physicists and engineers and provide materials growth support.
• Write R&D-level proposals for semiconductor materials and device technology advancements.
• Present R&D results at conferences and publish papers.

Minimum Requirements:

• Bachelor’s degree in Physics required. Full time position.

Additional Notes:

• Full time position
