Cryo-RF Probe Station for Superconductor/Semiconductor Electronics
Abstract
Recent advances in the integration of superconductors with semiconductors by epitaxy has made it possible to envision electronic dev ices that benefit from the capabilities inherently suited to the two disparate electronic phases of matter. While semiconductors are exceptional in switching and power amplification at high frequencies, superconductors retain quantum coherence across junctions and enable classical and quantum computation and communication schemes that remain unmatched by any other material family. Epitaxial su perconductor/semiconductor heterostructures thus enable new device structures that benefit qubits and single photon detectors, and h ave the potential to miniaturize, and seed new undiscovered device functionalities. Suchdevices must be systematically and carefull y characterized to understand their properties.To that end, we request funds for the acquisition of a Closed-Cycle Cryo-RF Probe St ation for the characterization of epitaxial superconductor/semiconductor heterostructures. The closed cycle cryogenic capability of the probe station will enable low-temperature measurements without the need for expensive liquid Helium. The RF probes will enable on-wafer measurements of multiple processed devices, significantly enhancing the throughput, and enabling a systematic exploration of variations across the wafer. Such systematic measurements will help clearly identify the advantages of epitaxial uperconductor/s emiconductor heterostructures over those processed by other techniques and will enable separating artefacts from genuine physical ph enomena.The requested equipment will be used by multiple research groups at Cornell University pursuing current projects supported by DoD. These projects range from identifying and controlling sources of quantum decoherence in epitaxial Josephson Junctions (Jena , PI), integration of SOT-MRAMs with Josephson Junction digital circuitry (Buhrmann, Senior Investigator), quantum microwave to opti cal transduction devices, single photon detectors, kinetic inductance parametric resonators, optomechanically transduced defect qubi ts, microwave spin resonance measurements, and superconductor/semiconductor resonant tunneling diodes, among others. It will be used for the training of graduate and undergraduate students, as well as researchers, in areas of interest to DoD, to prepare them for f uture careers in quantum computation and communication technologies.
