The High Lab studies optical and quantum science. We explore new methods to craft nanoscale interactions between light and low-dimensional solid state systems. By doing so, we can fundamentally modify materials, for instance by breaking time-reversal symmetry, or we can create deterministic, coherent interactions between single photons and quantum states. Our expertise integrates semiconductor physics, quantum optics, precision fabrication, plasmonics and integrated photonics. Currently, we are building next generation quantum technologies in diamond, exploring novel forms of interaction between quantum states, and exploring physics and technologies of excitons and correlated electrons in 2D materials.

Quantum engineering in diamond membranes

The High lab has an opening for a postdoctoral researcher to explore integrated quantum acoustic and quantum photonic technologies in diamond. The research will leverage our capabilities to generate diamond membranes that host coherent qubits and integrate the membranes into quantum material heterostructures, https://arxiv.org/abs/2306.04408. In particular, the research could utilize our capabilities to integrate diamond with lithium niobate and/or our capabilities to controllably generate strain in membranes, https://arxiv.org/abs/2307.11916. We are looking for a recent Ph.D. with experience in quantum, materials, and/or optical science. Please reach out to Alex (ahigh@uchicago.edu) with any inquiries!

Materials Synthesis for Microelectronics and Quantum Devices in Silicon Carbide

The High Lab at UChicago has an opening for a postdoctoral fellow to develop novel methods for silicon carbide (SiC) membrane generation for applications in microelectronics and quantum technologies. The research will explore chemical vapor deposition (CVD) of material heterostructures and other advanced material growth and fabrication techniques. The successful candidate will work closely with collaborators at Argonne National Laboratory to leverage a novel hard X-ray compatible SiC CVD instrument developed to characterize material growth in real time. There will also be an opportunity to carry out some of the first experiments at the upgraded Advanced Photon Source (APS). The candidate will also work closely with scientists in the Quantum Foundry. Candidates a background in any of the following are encouraged to apply: thin film synthesis - especially CVD, nanofabrication, wide bandgap electronics, electrochemistry. Candidates should also be familiar with materials characterization tools, including Raman spectroscopy and XRD. Interested candidates should send a full CV and statement of interest to Alex at ahigh@uchicago.edu and Katherine Harmon at kharmon@anl.gov.
