Fabry–Pérot resonances and a crossover to the quantum Hall regime in ballistic graphene quantum point contacts
We report on the observation of quantum transport and interference in a graphene device that is attached with a pair of split gates to form an electrostatically-defined quantum point contact (QPC). In the low magnetic field regime, the resistance exhibited Fabry–Pérot (FP) resonances due to np’n(pn’...
