文摘
Junction angle dependency of Andreev reflection (AR) and bound states is studied. Potential barrier induced spin rotation causes junction angle dependent AR. Step and planar normal-superconductor junction shows distinct conductive behavior. Dirac cone ellipticity affects Andreev bound state in step Josephson junction. Josephson current can be tuned using potential barrier at the junction.
