Project Description

A Superconducting Quantum Interference Device (SQUID) is a sensitive magnetometer. By coupling it to a scanning probe, it can serve as a tool to image local magnetic fields with sub-micron spatial resolution. This instrument is known as a Scanning SQUID Microscope (SSM). My project involves building and developing an SSM with a small superconducting loop on the vertex of a Silicon wafer. We’d like to use this instrument to image the current density in Superconducting-Topological Insulator Josephson junctions as well as other quantum materials.
