Multifunctional Oxide Films for Advanced Multifunction RF Systems
Abstract
The Electro-Optics Center of the Pennsylvania State University procured and established a custom-designed molecular beam epitaxy (MBE) system and commenced growth of oxide (TiO2, STO, BTO, BST and MgO) and III-nitride (AIN, GaN) thin films, The growth parameters and layer properties of these films were investigated by various in-situ and ex-situ characterization techniques under the aspect of developing a AIGaN HEMT epitaxy process, a BST varactor epitaxy process and aiding the integration of BST epitaxy on III-nitride templates using MgO buffer layers. Methods for the dielectric characterization of the epitaxial oxide films have been evaluated and applied in collaboration with Dr. Lanagan (Penn State Materials Research Laboratory).
