Tunable transmission of quantum Hall edge channels with full degeneracy lifting in split-gated graphene devices

Tunable transmission of quantum Hall edge channels with full degeneracy lifting in split-gated graphene devices

Quantum point contacts are gate-tunable constrictions allowing for control of charge carrier transmission in 2D electron gases. Here, the authors fabricate a hBN/graphene/hBN van der Waals heterojunction to enable quantum point contact devices in the integer and fractional quantum Hall regimes.
