The Analytical Microscopy Group at the National Renewable Energy Laboratory (NREL) has an opening for a Post Doctoral Fellow to carry out TEM/STEM characterization of polycrystalline thin film structures for photovoltaic applications. Particular emphasis will be on the examination of structural defects, phase formation, and interfaces in polycrystalline compound semiconductors. The goal of the research is to correlate the structural and compositional properties with the micro-electrical properties and the solar cell parameters. Experience with Z-contrast, EELS and EDS analysis is highly desirable. Interested candidates are asked to submit a resume and three recent publications to Dr. Mowafak Al-Jassim; firstname.lastname@example.org.
