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…
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…
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…
Optimizing the Optical and Electrical Properties of Graphene Ink Thin Films by Laser-annealing
Sepideh Khandan Del, Rainer Bornemann, Andreas Bablich +6
We demonstrate a facile fabrication technique for graphene-based transparent conductive films. Highly flat and uniform graphene films are obtained through the incorporation of an e…
Electromechanical Piezoresistive Sensing in Suspended Graphene Membranes
A. D. Smith, F. Niklaus, A. Paussa +9
Monolayer graphene exhibits exceptional electronic and mechanical properties, making it a very promising material for nanoelectromechanical (NEMS) devices. Here, we conclusively de…
A Simple Route towards High-Concentration Surfactant-Free Graphene Dispersions
Jiantong Li, Fei Ye, Sam Vaziri +3
A simple solvent exchange method is introduced to prepare high-concentration and surfactant-free graphene liquid dispersion. Natural graphite flakes are first exfoliated into graph…
