Abstract

An electron cooling junction using platinum silicide as a superconductor contact is demonstrated for the first time. The junction shows encouraging electrical characteristics and a fit to a standard cooling model predicts cooling from 100 mK to 50 mK for a test device. Silicides have been widely used in the semiconductor industry because of their reliability and reduced contact resistance; hence this technology could find wider application in a silicon-based electron refrigerator.
