Vertical Graphene Base Transistor
Wolfgang Mehr, J. Christoph Scheytt, Jarek Dabrowski +5
We present a novel, graphene-based device concept for high-frequency operation: a hot electron graphene base transistor (GBT). Simulations show that GBTs have high current on/off r…
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…
Charge transfer and trapping as origin of a double dip in the transfer characteristics of graphene based field-effect transistors
Antonio Di Bartolomeo, Filippo Giubileo, Salvatore Santandrea +4
We discuss the origin of an additional dip other than the charge neutrality point observed in transfer characteristics of graphene-based field-effect transistors. The double-dip is…
