New Technique to Fabricate Semiconductors from Graphene
Description Dr. Helge Weman and Professor Bjørn-Ove Fimland, researchers from the Norwegian University of Science and Technology (NTNU), have become the first in the world to devise a technique for for semiconductor production from graphene. A network of semiconductor nanowires is grown on graphene by bombarding its surface with arsenic molecules and gallium atoms. The result is a 1-µm thick hybrid material that behaves as a semiconductor. By contrast, existing silicon semiconductors have several hundred folds thickness and their electrical conductivity gets affected by light, temperature or the inclusion of other atoms.
