Grzegorz Lupina,Julia Kitzmann,Ioan Costina,Mindaugas Lukosius,Christian Wenger,Andre Wolff,Sam Vaziri,Mikael Östling,Iwona Pasternak,Aleksandra Krajewska,Wlodek Strupinski,Satender Kataria,Amit Gahoi,Max C. Lemme,Guenther Ruhl,Guenther Zoth,Oliver Luxenhofer,Wolfgang Mehr +17 more
TL;DR: Graphene layers grown on copper foils by chemical vapor deposition and transferred to silicon wafers by wet etching and electrochemical delamination methods with respect to residual submonolayer metallic contaminations are investigated.
Journal ArticleDOI
A Graphene-Based Hot Electron Transistor
Sam Vaziri,Grzegorz Lupina,Christoph Henkel,Anderson D. Smith,Mikael Östling,Jarek Dabrowski,Gunther Lippert,Wolfgang Mehr,Max C. Lemme,Max C. Lemme +9 more
TL;DR: Graphene-based hot electron transistors, which are called graphene base transistors (GBT), can be carried out at the wafer scale with standard silicon technology and show ON/OFF current ratios exceeding 10(4).
Journal ArticleDOI
Vertical Graphene Base Transistor
Wolfgang Mehr,Jarek Dabrowski,Johann Christoph Scheytt,Gunther Lippert,Ya-Hong Xie,Max C. Lemme,Mikael Östling,Grzegorz Lupina +7 more
TL;DR: In this article, a hot-electron graphene base transistor (GBT) is proposed for high-frequency operation, which can potentially allow terahertz operation, based on energy-band considerations.
Journal ArticleDOI
Tunable Schottky barrier and high responsivity in graphene/Si-nanotip optoelectronic device
Antonio Di Bartolomeo,Filippo Giubileo,Giuseppe Luongo,Laura Iemmo,Nadia Martucciello,Gang Niu,Mirko Fraschke,Oliver Skibitzki,Thomas Schroeder,Grzegorz Lupina +9 more
TL;DR: In this article, the authors demonstrate tunable Schottky barrier height and record photo-responsivity in a new concept device made of a single-layer CVD graphene transferred onto a matrix of nanotips patterned on n-type Si wafer.
Journal ArticleDOI
Vertical Graphene Base Transistor
Wolfgang Mehr,J. Christoph Scheytt,Jarek Dabrowski,Gunther Lippert,Ya-Hong Xie,Max C. Lemme,Mikael Östling,Grzegorz Lupina +7 more
TL;DR: In this paper, a hot electron graphene base transistor (GBT) was proposed for high frequency operation, which has high current on/off ratios and high current gain and is compatible with SiGe process lines.
