Research Opportunities

Physics students are involved in the Microwave Group both part-time during the school year and full time for ten or eleven weeks during the summer. Students who do research during the school year are in a much better position to receive a summer research assistantship. This is true for any group. Physics research requires physics knowledge. Therefore, a record of enthusiastically taking physics courses is absolutely required. Research is a multi-year commitment. Sometimes you get credit for it (PHYS 490), occasionally you might even get paid, but usually you do it just because you want to do it. You will be asked to make a long-term commitment until graduation as a condition for any paid research opportunity. See the list of courses above to understand what will ultimately be expected of you academically.

Collaborators Welcome

Collaborators are sought for microwave superconductivity research. We have facilities and HTS materials to carry out such research including network and spectrum analyzers to 22 GHz, broadband power amplifiers, furnaces, cryogenic cooling, wire bonding, die attachment, and a large supply of HTS wafers and patterned resonator and filter samples.

We also have large inventory of 2" diameter TBCCO-2212 wafers and patterned HTS microwave resonators available for use in collaborative research. Proposals are welcome!
