Graphene — a single layer of carbon atoms arranged in a honeycomb lattice — is already attracting interest for its various applications in electronics and optoelectronics, including its use as ...

It is one of those ... an ultrathin layer of silicon dioxide on top, the graphene flakes, which are just half a nanometre thick, become visible under an ordinary optical microscope.

Needless to say, there’s a little bit of hype surrounding graphene. For the last several years, one of the most interesting ... preferably with an electron microscope, with baited breath.

successfully developed the special in-situ transmission electron microscope technique to measure the current-voltage curve of graphene nanoribbon (GNR) with observing the edge structure and found ...

The situation changes, however, when graphene, a single layer of carbon atoms arranged in a honeycomb lattice, is used instead of a common iron or copper wire. In graphene, impurity collisions are ...
