Conductivity at the edges of graphene bilayers

ScienceDaily   -   General News Websites

For nanoribbons of bilayer graphene, whose edge atoms are arranged in zigzag patterns, the bands of electron energies which are allowed and forbidden are significantly different to those found in monolayer graphene. This causes variations in the w...
