Developing a testbed for in-situ implantation of ionic defects into high purity ZnO
Abstract
This proposal is intended to support the development of ultra-high purity quantum materials of interest to the Air Force Office of Scientific Research. The focus is on the acquisition of components to build a custom high vacuum deposition chamber for depositing high purity ZnO thin films. The chamber will integrate cutting edge technology such as laser heating and liquid ozone as an oxidizer in order to achieve high purities. In these thin films, we plan to introduce small concentrations of defects and study their quantum coherence properties. The test chamber is intended to facilitate screening of a large number of chemical defects rapidly across a large thermodynamic window during the growth procedure. This effort will be supported by ab initio calculations and optical spectroscopy of defects as part of a larger collaborative research program to study the quantum coherence properties of defects, with potential applications in quantum processing, sensing, and communication. The chamber will be a testbed for complex heterostructuring recipes, as well as the synthesis of ZnO with nuclear isotope refined source materials, which is a defining goal of this research program. The proposal also looks to support these crystal growth efforts by establishing high end diffraction tools which will underpin detailed structural analysis of ZnO, as well as other intermetallic quantum materials currently under study in the condensed matter physics program, with a focus on studying the correlations between structural and electronic properties of quasi-two dimensional layered compounds.
