Resistive Graphene Humidity Sensors with Rapid and Direct Electrical Readout
Anderson David Smith, Karim Elgammal, Frank Niklaus +11
We demonstrate humidity sensing using a change of electrical resistance of a single- layer chemical vapor deposited (CVD) graphene that is placed on top of a SiO2 layer on a Si waf…
Bilayer Insulator Tunnel Barriers for Graphene-Based Vertical Hot-electron Transistors
Sam Vaziri, Melkamu Belete, Eugenio Dentoni Litta +4
Vertical graphene-based device concepts that rely on quantum mechanical tunneling are intensely being discussed in literature for applications in electronics and optoelectronics. I…
Molecular beam growth of graphene on mica
Gunther Lippert, Jarek Dabrowski, Yuji Yamamoto +5
We demonstrate molecular beam growth of graphene on biotite mica substrates at temperatures below 1000°C. As indicated by optical and atomic force microscopy, evaporation of carbon…
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…
