The Development of Scanning Microwave Microscope for High-Throughput Characterization of Dielectric and Conducting Materials at Low Temperatures

摘要

We developed a scanning microwave microscope (S|.LM) designed for characterizing local electric properties at low temperatures. A high-Q V4coaxial cavity was used as a sensor probe, which can detect the cliange of quality factor due to the tip-sample interaction with enough accuracy. From the measurements of combinatorial samples, it was demonstrated that this S).iM system has enough performance for high-throughput characterization of sample conductance under variable temperature conditions.
