Silicon may be replaced by graphene in semiconductors

The Research Council of Norway has announced the development of a method to produce semiconductors with graphene instead of silicon.  In what is expected to lower manufacturing costs of semiconductor components, graphene will also allow hundreds of times thinner and stronger designs.  Dr Weman from the Norwegian University of Science and Technology says that due to graphene’s transparency and pliability characteristics, that graphene

 “may bring about a revolution in the production of solar cells and LED components. Windows in traditional houses could double as solar panels or a TV screen. Mobile phone screens could be wrapped around the wrist like a watch. In short, the potential is tremendous.”

Graphene is a single networked layer of carbon atoms that are arranged in an hexagonal pattern that is not affected by temperature or light.  By bombarding graphene with gallium atoms and arsenic molecules, a series of nanowires are grown creating a nanowire network on the graphene, which turns it into a hybrid material semiconductor.

Companies such as IBM and Samsung have shown interest in producing semiconductors with graphene.
