Chaotic quantum transport near the charge neutrality point in inverted type-II InAs/GaSb field-effect transistors
Chaotic quantum transport near the charge neutrality point in inverted type-II InAs/GaSb field-effect transistors
We present here our recent quantum transport results around the charge neutrality point (CNP) in a type-II InAs/GaSb field-effect transistor. At zero magnetic field, a conductance minimum close to 4e2/h develops at the CNP and it follows semi-logarithmic temperature dependence. In quantized magnetic (B) fields and at low temperatures, well …
