DURIP Improving the yield of superconductor-semiconductor materials using fast photoluminescence and Hall measurement
Abstract
[Office of Naval Research: Dan Gunlycke (312)]We are requesting funds to purchase a cryogenic optical access cryostat that integrates photoluminescence and Hall measurement. This will greatly enhance our screening of semiconductor and indirectly superconductor growth for mesoscopic and topological physics based on III/V and Al materials. This equipment package will be devoted to measurements of superconducting-semiconductor hybrid devices and qubits projects already funded by ONR MURI, AFOSR and ARO. Materials synthesis without a fast and efficient feedback loop is quite inefficient. Room temperature and cryogenic analysis of structural and electronicproperties of epi materials should happen in less than a day to enable efficient planning and design of the next wafer for the following day. The proposed system will enhance our research capabilities in several crucial ways: (1) It will allow us to study the interface qualities of III-V quantum wells and quantum dots. We currently do not have these capabilities. (2) These pieces of equipmentwill allow us to screen electronic properties such as electron mobility and density in a timely fashion. (3) Lastly, they will integrate structural and electronic properties into one measurement (~6hr). This document is publicly releasable.
