Ripples and Warping of Graphene: A Theoretical Study
08 Jun 2010  Online Presentations  Contributor(s): Umesh V. Waghmare
We use firstprinciples density functional theory based analysis to understand formation of ripples in graphene and related 2D materials. For an infinite graphene, we show that ripples are linked...
