I am just curious why quantum Hall effect is so important for graphene? What is the application or implication other than calculating the carrier mobility using this process?
For metal evaporation, cost of Au and Pd pallets are comparable. But in most of the cases, Au electrode is widely used though the work function of graphene under Au is lower than graphene under...
