Project Description: |
Can you measure the resistance of a superconductor? If so, does the resistance have an influence on devices fabricated with superconductors? You will use a microwave sapphire resonator to measure the surface resistance of superconducting thin films. Some of the films have been patterned into devices and your research will examine their device properties. In your research you can probe the electrical nonlinearity near the superconducting phase transition, compare the nonlinearities of different superconducting materials, and investigate the effects of device fabrication on nonlinearity. You will learn the tools of the trade in high frequency engineering including microwave test and measurement, electromagnetic design and analysis (EDA), and microwave device packaging. This research will include some classroom instruction on the research topic along with required group meetings.
