This study investigates quantized electron transport in high-mobility quantum point contact (QPC) devices in hBN/graphene/hBN in the quantum Hall regime. This study primarily focuses on the effect of the gap width of split gates on edge-channel manipulations, which defines the QPC structure and its...
