Spatially resolved photocurrents in graphene nanoribbon devices

Klaus Kern, Kannan Balasubramanian, Stephan Rauschenbach, Marko Burghard, Adarsh Singh Sagar, Thomas Dufaux

We present here a scanning photocurrent microscopy study of individual graphene nanoribbons, revealing pronounced photocurrent responses close to the nanoribbon/metal contacts. The magnitude of the corresponding photocurrent signal was found to be directly ...

Electric field effect in graphite crystallites

Klaus Kern, Kannan Balasubramanian, Marko Burghard, Adarsh Singh Sagar

Graphite is a highly anisotropic crystal with a quasi-two-dimensional electronic structure exhibiting high intrinsic charge carrier mobility. Here, we investigate the effect of an electric field on the resistance of individual graphite crystallites with a ...

Graphene-based Field-effect Transistors

Adarsh Singh Sagar

With transistors set to reach their smallest possible size in the next decade, the silicon chip is likely to change dramatically, or be replaced entirely. The transistor industry's path which has been largely shaped by Gordon Moore's famous prediction that ...
