Robust quantum point contact operation of narrow graphene constrictions patterned by AFM cleavage lithography
Abstract Detecting conductance quantization in graphene nanostructures turned out more challenging than expected. The observation of well-defined conductance plateaus through graphene nanoconstrictions so far has only been accessible in the highest quality suspended or h-BN encapsulated devices. How...
