Nonequilibrium ac Josephson effect in mesoscopic Nb-InAs-Nb junctions
K. W. Lehnert, N. Argaman, H. -R. Blank +4
Microwave irradiation of Nb-InAs-Nb junctions reveals frequency-doubled Josephson currents which persist to high temperatures, in the absence of a critical current. A nonequilibriu…

Current-voltage characteristics of semiconductor-coupled superconducting weak links with large electrode separations
M. Thomas, H. R. Blank, K. C. Wong +2
We have studied the current-voltage characteristics of superconducting weak links in which the coupling medium is the 2-D electron gas in InAs-based semiconductor quantum wells, wi…
