Electron Transport across Vertical Silicon / MoS / Graphene Heterostructures: Towards Efficient Emitter Diodes for Graphene-Base Hot Electron Transistors
Melkamu Belete, Olof Engström, Sam Vaziri +4
Heterostructures comprising of silicon (Si), molybdenum disulfide (MoS) and graphene are investigated with respect to the vertical current conduction mechanism. The measured…
Direct growth of low-doped graphene on Ge/Si(001) surfaces
J. Dabrowski, G. Lippert, J. Avila +12
The practical difficulties to use graphene in microelectronics and optoelectronics is that the available methods to grow graphene are not easily integrated in the mainstream techno…
Going Ballistic: Graphene Hot Electron Transistors
Sam Vaziri, Anderson D. Smith, Mikael Östling +11
This paper reviews the experimental and theoretical state of the art in ballistic hot electron transistors that utilize two-dimensional base contacts made from graphene, i.e. graph…
Graphene Grown on Ge(001) from Atomic Source
Gunther Lippert, Jarek Dabrowski, Thomas Schroeder +8
Among the many anticipated applications of graphene, some - such as transistors for Si microelectronics - would greatly benefit from the possibility to deposit graphene directly on…
A Graphene-based Hot Electron Transistor
Sam Vaziri, Grzegorz Lupina, Christoph Henkel +6
We experimentally demonstrate DC functionality of graphene-based hot electron transistors, which we call Graphene Base Transistors (GBT). The fabrication scheme is potentially comp…
Direct Graphene Growth on Insulator
Gunther Lippert, Jarek Dabrowski, Max C. Lemme +3
Fabrication of graphene devices is often hindered by incompatibility between the silicon technology and the methods of graphene growth. Exfoliation from graphite yields excellent f…
