Congratulations Katherine Ziemer
Dr. Ziemer's research involves engineering surfaces in order to integrate wide bandgap semiconductors with functional and multi-functional oxides, organic molecules, and/or biomaterials. Dr. Ziemer's group, in the Interface Engineering Laboratory, takes advantage of the ultra-high vacuum environment to study, at the atomic level, the growth and processing of thin films and nanostructures. This "surface engineering" is based on the hypothesis that understanding the atomic-level interactions at a surface will lead to developing processes to create new materials and to effectively interface different materials for new functionalities. The tools used for growth and formation mechanism studies are solid source effusion cells, plasma sources, ion sources, atom sources, and the in-situ analysis tools of reflection high-energy electron diffraction (RHEED), Auger electron spectroscopy (AES), and x-ray photoelectron spectroscopy (XPS).
