2D Materials-based Quantum Device Fabrication Processes at the MonArk NSF Quantum Foundry

The MonArk NSF Quantum Foundry is a research program jointly operated by the University of Arkansas and Montana State University with a goal to accelerate and democratize the fabrication of quantum devices based on 2D materials. A major element of MonArk is a user and collaborator program for the fabrication and/or characterization of devices designed by external users and collaboration. This talk will provide an overview of the foundry services, which include bulk crystal synthesis, robotic exfoliation, cataloging, and stacking of 2D materials, lithography, deposition, etching, and packaging, all within a system of interconnected gloveboxes. Characterization capabilities include a dilution refrigerator for DC to microwave measurements, an optoelectronic cryostat, SQUID magnetometer, and various visible to near-infrared optical spectroscopy techniques. Example collaborative projects will be highlighted, including high mobility graphene devices and voltage tunable semiconductor/ superconductor hybrid devices.
