Perfect Andreev Reflection of Helical Edge Modes in InAs/GaSb Quantum Wells
Ivan Knez, Rui-Rui Du, Gerard Sullivan
We present an experimental study of inverted InAs/GaSb composite quantum wells in the hybridization regime and contacted by superconducting electrodes. A front gate is used to vary…

Evidence for Helical Edge Modes in Inverted InAs/GaSb Quantum Wells
Ivan Knez, Rui-Rui Du, Gerard Sullivan
We present an experimental study of low temperature electronic transport in the hybridization gap of inverted InAs/GaSb composite quantum wells. Electrostatic gate is used to push…
