Abstract
The supercurrent in a Nb-In0.53Ga0.47As/In0.77Ga0.23As/InP weak link s tructure is controlled by means of a current injected into the two- di mensional electron gas. For small injection currents the critical curr ent to control current ratio is as large as 20. The measured features can be qualitively explained in terms of a modification of the Andreev level occupation by the injected carriers. (C) 1998 American Institut e of Physics.
