Giant Surface Charge Density of Graphene Resolved From Scanning Tunneling Microscopy and First-Principles Theory
P. Xu, Y. Yang, S. D. Barber +6
In this work, systematic constant-bias, variable-current scanning tunneling microscopy (STM) measurements and STM simulations from density-functional theory are made, yielding crit…
