Probing Charging and Localization in the Quantum Hall Regime by Graphene pnp Junctions
Jairo Velasco, Gang Liu, Lei Jing +4
Using high quality graphene pnp junctions, we observe prominent conductance fluctuations on transitions between quantum Hall (QH) plateaus as the top gate voltage Vtg is varied. In…
