Here comes semiconductors made from graphene!

BANGALORE, INDIA:Researchers at the Norwegian University of Science and Technology (NTNU) have developed a method for producing semiconductors from graphene. As per the researchers, this could be done by growing semiconductor nanowires on graphene.

Graphene, which is the thinnest yet the strongest material, consists of a single layer of carbon atoms that is both flexible and transparent. It is cheaper to produce and is a good conductor of heat and electricity.

"Given that it's possible to make semiconductors out of graphene instead of silicon, we can make semiconductor components that are both cheaper and more effective than the ones currently on the market," said Helge Weman of the Norwegian University of Science and Technology (NTNU).

A network of minute nanowires was created after the researchers bombed the graphene surface with gallium atoms and arsenic molecules. As a resultant, a one-micrometre thick hybrid material was formed which was a good semiconductor material.

"A material comprising a pliable base that is also transparent opens up a world of opportunities, one we have barely touched the surface of. This 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," said the researchers.

The researchers have been in touch with electronic giants such as Samsung and IBM for creating prototypes directed towards specific areas of applications. In about five years, the new semiconductor hybrid material could be expected in commercial market.
