Semiconductors made from graphene and boron nitride can be charge-doped using light. When the GBN heterostructure is exposed to light (green arrows), positive charges move from the graphene layer (purple) to boron nitride layer (blue). Credit: Image courtesy of Feng Wang, Berkeley Lab

Georgia Tech professor Ian Akyildiz poses with a schematic showing how surface plasmon polariton (SPP) waves would be formed on the surface of tiny antennas fabricated from graphene. The technology could allow networks of nanomachines to communicate. Credit: Georgia Tech Photo: Rob Felt

Graphene Nano Networks Offer Promise

This is an optical microscope image of a copper film mostly destroyed during graphene growth. What was a continuous copper film has decomposed into grey areas of bare sapphire, rings and irregular patches of copper that appear in a rainbow of colors due to oxidation, and small star-shaped islands of graphene, which appear bright because the graphene protects the copper from oxidation.

After decoration with maghemite nanoparticles the graphene spontaneously form nanoscrolls. The dark cylinders in the upper part of the image shows graphene nanoscrolls that are covered with a smooth layer of small particles. The nanoscrolls form "bundles" with 5-10 cylinders due to the interaction between the nanoscrolls. The lower part of the image show a simulated image of a graphene sheet in the scrolling process. The region zoomed show a maghemite nanoparticle attached to the graphene sheet.
