Fabrication and Studies of Silicide-Based Superconducting Nanowires

Several silicide compounds are promising materials for studies and applications of quantum phase slips (QPS) in superconducting nanowires (SNWs). This paper describes two nanofabrication processes, which were applied to manufacture silicide SNWs. Experiments on MoSi nanowires indicate size dependent crossover from conventional superconductivity to transport influenced by thermal and quantum fluctuations. Results of the first experiments on other silicide SNWs will be presented in the conference.
