Kavli Affiliate: Ke Wang | First 5 Authors: Wei Ren, Xi Zhang, Jaden Ma, Xihe Han, Kenji Watanabe | Summary: We present a device architecture of hybrid-edge and dual-gated quantum point contact. We demonstrate improved electrostatic control over the separation, position, and coupling of each broken-symmetry compressible strip in graphene. Via low-temperature magneto-transport measurement, we […]
