Nanowires on graphene

A group from the Norwegian University of Science & Technology (NTNU) in Trondheim have reported and patented the growth of GaAs nanowires on graphene. These nanowires are hexagonal cross section and vertically aligned. Following the initial MBE deposition of Ga and Ga droplet formation, the subsequent addition of an As beam leads through a vapour-liquid-solid mechanism to vertical GaAs nanowire growth at the graphene - Ga droplet interface. The group aim to commercialise this work through CrayoNano AS, a spin out company from NTNU, with the fabrication of efficient and flexible LEDs and solar cells.
