Plasma-enhanced chemical vapor deposition of amorphous Si on graphene
G. Lupina, C. Strobel, J. Dabrowski +8
Plasma-enhanced chemical vapor deposition of thin a-Si:H layers on transferred large area graphene is investigated. Radio frequency (RF, 13.56 MHz) and very high frequency (VHF, 14…
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…
Deposition of thin silicon layers on transferred large area CVD graphene
Grzegorz Lupina, Julia Kitzmann, Mindaugas Lukosius +3
Physical vapor deposition of Si onto transferred graphene is investigated. At elevated temperatures, Si nucleates preferably on wrinkles and multilayer graphene islands. In some ca…
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…
Nucleation and growth of HfO layers on graphene by CVD
Grzegorz Lupina, Mindaugas Lukosius, Julia Kitzmann +3
A seed layer-free growth of HfO on commercially available CVD graphene from various suppliers is investigated. It is revealed that the samples of monolayer graphene transferred…
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…
