Imaging charge density fluctuations in graphene using Coulomb blockade spectroscopy
A. Deshpande, W. Bao, H. Zhang +3
Using scanning tunneling microscopy, we have imaged local charge density fluctuations in monolayer graphene. By placing a small gold nanoparticle on the end of the STM tip, a charg…
