They will perform epitaxial growth of compound semiconductor device structures, characterize materials, document procedures, develop new processes, carry out all necessary maintenance of the growth reactor and ancillary equipment, ensure that all appropriate safety measures are carried out, and interface with in-house epitaxial material customers. Characterize epitaxial material using optical microscope, X-ray diffraction, photoluminescence, electrochemical CV profiling, and Hall effect measurements and make process adjustments with minimal supervision.
