Intrinsic and extrinsic corrugation of monolayer graphene deposited on SiO2
V. Geringer, M. Liebmann, T. Echtermeyer +5
Using scanning tunneling microscopy (STM) in ultra high vacuum and atomic force microscopy, we investigate the corrugation of graphene flakes deposited by exfoliation on a Si/SiO2…
Non-volatile switching in graphene field effect devices
T. J. Echtermeyer, M. C. Lemme, M. Baus +3
The absence of a band gap in graphene restricts its straight forward application as a channel material in field effect transistors. In this letter, we report on a new approach to e…
A graphene-based electrochemical switch
T. J. Echtermeyer, M. C. Lemme, M. Baus +3
Conventional field effect transistor operation in graphene is limited by its zero gap and minimum quantum conductivity. In this work, we report on controlled electrochemical modifi…
