Negative Fermi-level Pinning Effect of Metal/n-GaAs(001) Junction with Graphene Interlayer
Hoon Hahn Yoon, Wonho Song, Sungchul Jung +6
It is demonstrated that the electric dipole layer due to the overlapping of electron wavefunctions at metal/graphene contact results in negative Fermi-level pinning effect on the r…
