Does the schottky barrier occur in a graphene/metal contact? I will appreciate any reference on that
Schottky barrier formed via metal/semi-conductor while Graphene is conductor. All the metal contacts on metal will be ohmic and metal/graphene will result into ohmic contact. However, Si/graphene could generate Schottky barrier.
I am getting so many warnings. Is this what I should expect? sylvester@sylvester-HP-EliteBook-840-G2:~/Applications/boltztrap-1.2.5/src$ make clean rm -f *.o *.mod *.pc *.pcl...
