High On/Off Ratios in Bilayer Graphene Field Effect Transistors Realized by Surface Dopants
Bartholomaeus N. Szafranek, Daniel Schall, Martin Otto +2
The unique property of bilayer graphene to show a band gap tunable by external electrical fields enables a variety of different device concepts with novel functionalities for elect…
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…
Time-resolved broadband analysis of slow-light propagation and superluminal transmission of electromagnetic waves in three-dimensional photonic crystals
J. Gomez Rivas, A. Farre Benet, J. Niehusmann +2
A time-resolved analysis of the amplitude and phase of THz pulses propagating through three-dimensional photonic crystals is presented. Single-cycle pulses of THz radiation allow m…
