Abstract

Graphene is a single atom thick sheet of carbon atoms with many interesting properties. Graphite is composed of multiple layers of graphene, so it can be mechanically separated into flakes of graphene. Graphene was separated from pure graphite samples using conventional scotch tape and analyzed optically to determine thickness. Graphite oxide was also reduced using a laser to form bans of graphene on various substrates. It was shown that the electrical properties of the graphite oxide differed after laser treatment, indicating varying levels of graphene present in the treated samples.
