Hello, if I use hBN below graphene as bio-transistor, will the dirac point shifted compared with using only graphene in transistor?
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...
