Graphene Nanomesh

Graphene is a flat sheet of carbon atoms packed into a honeycomb like structure that is only one atom thick. Hexagonal Boron Nitride is a synthetically created ceramic that has a microstructure similar to graphite. A single layer of this substance is called a “nanomesh” which looks like an assembly of hexagonal pores. UCLA researchers have created a new structure from graphene that they call “graphene nanomesh”. Previously, graphene has not been shown to function effectively as a semiconductor. This new structure creates a semiconducting thin film.

In research to be published in the March issue of Nature Nanotechnology (currently available online), Huang’s team reveals the creation of a new graphene nanostructure called graphene nanomesh, or GNM. The new structure is able to open up a band gap in a large sheet of graphene to create a highly uniform, continuous semiconducting thin film that may be processed using standard planar semiconductor processing methods.

“In conjunction with recent advances in the growth of graphene over a large-area substrate, this concept has the potential to enable a uniform, continuous semiconducting nanomesh thin film that can be used to fabricate integrated devices and circuits with desired device size and driving current. The concept of the GNM therefore points to a clear pathway towards practical application of graphene as a semiconductor material for future electronics. The unique structural and electronic characteristics of the GNMs may also open up exciting opportunities in highly sensitive biosensors and a new generation of spintronics, from magnetic sensing to storage,” she concludes.
