Gate dependent photocurrents at a graphene p-n junction

Klaus Kern, Marko Burghard, Eduardo Jian Hua Lee, Eva Carmen Peters

We have used scanning photocurrent microscopy to explore the electronic characteristics of a graphene p-n junction fabricated by local chemical doping of a graphene sheet. The photocurrent signal at the junction was found to be most prominent for gate volt ...

Electrical Properties and Photoconductivity of Stacked-Graphene Carbon Nanotubes

Klaus Kern, Marko Burghard, Eduardo Jian Hua Lee

Stacked-graphene carbon nanotubes (SG-CNTs) obtained via pyrolysis of columnar superstructures of polycyclic aromatic hydrocarbons are studied by electrical transport measurements and scanning photocurrent microscopy. The charge transport in individual SG- ...

Spatially Resolved Potential Distribution in Carbon Nanotube Cross-Junction Devices

Klaus Kern, Marko Burghard, Kannan Balasubramanian, Eduardo Jian Hua Lee

Crossed-nanotube junctions, the basic constituents of carbon nanotube networks, are investigated by scanning photocurrent microscopy. The location of the predominant electrostatic potential drop, at the electrical contacts or at the junction, is found to b ...
