Project Description:

This interdisciplinary project will incorporate the disciplines of Physics and Chemistry. However the project is specifically housed within the Hope College Department of Physics and requires course preparation in physics. ===> The advancement of tomorrow’s technology builds on today’s research in functional and advanced materials. Layer-by-layer controlled growth of perovskite thin films are producing new piezoelectric superlattices for piezo power generation. The deposition of MgB2 thin films by hybrid physical-chemical vapor deposition promises the clean performance of low temperature superconductors in a high temperature superconducting material. New direct-gap semiconductors promise higher efficiency photovoltaic solar cells. Whether materials are grown epitaxially or assembled layer-by-layer, process advancement depends on systematic feedback from ex-situ analysis of the resulting material. The Hope Ion Beam Accelerator Laboratory (HIBAL) is capable of providing this useful feedback on film deposition and growth, and this project will use the accelerator to produce those badly needed characterizations. ===> You will work within the Microwave Group in the Physics Department on Rutherford backscattering (RBS) analysis of the materials which are prepared by our collaborators at laboratories around the world. You will be expected to become a radiation safety trained accelerator operator. This work will include use of the scanning electron microscope since energy dispersive X-ray analysis is a useful preliminary analysis. You will also gain a strong working knowledge of the materials being studied. Besides collecting data from the accelerator, you will analyze the results by modelling and fitting. You will also prepare reports for the collaborators. While not occupied with this project, be prepared to work on other research matters in the Microwave Lab. This work relies on you already possessing a significant knowledge base in physics and applicants who do not enthusiastically pursue courses in physics will not be considered. A minimum of one year of calculus based physics at the college level is required. You must also have a good working knowledge of fundamental chemistry. CHEM 126 or 131 are strongly recommended.
