Andreev Reflection in the Quantum Hall Regime at an Al/InAs Junction on a Cleaved Edge
Takafumi Akiho, Hiroshi Irie, Yusuke Nakazawa +3
We have fabricated a superconductor/semiconductor (S/Sm) junction composed of Al and InAs using cleaved edge overgrowth. By exploiting the unique geometry with a thin Al/Pt/Al tril…
