Tuning the graphene work function by electric field effect
Young-Jun Yu, Yue Zhao, Sunmin Ryu +3
We report variation of the work function for single and bi-layer graphene devices measured by scanning Kelvin probe microscopy (SKPM). Using the electric field effect, the work fun…

Probing the Intrinsic Properties of Exfoliated Graphene: Raman Spectroscopy of Free-Standing Monolayers
Stephane Berciaud, Sunmin Ryu, Louis E. Brus +1
The properties of pristine, free-standing graphene monolayers prepared by mechanical exfoliation of graphite are investigated. The graphene monolayers, suspended over open trenches…
