Implementation of high frequency techniques for hybrid superconductor-semiconductor devices
Abstract
Hybrid superconductor-semiconductor devices are currently at the center of intensive experimental study owing to their rich phenomenology and to their potential in quantum technologies [1, 2]. Because of the growing complexity of experiments, techniques employing high frequency signals appear as powerful tools for performing faster measurements [3] and for gaining new insights on the physics of the devices beyond those obtained with DC transport [4]. In this work, I will present our ongoing efforts to implement high frequency techniques for studying devices based on proximitized nanowires. I will present our preliminary results of RF reflectometry measurements benchmarking them against DC transport, specifically concerning the SNR with respect to the required measurement time. I will also discuss our first measurements of Shapiro steps in Josephson junctions based on hybrid InAs-Al nanowires.
