Abstract
Graphene is a very interesting new material, and promises attractive applications in future nanodevices. It is a 2D carbon structure with very interesting physical behavior. Graphene is an almost transparent material that has higher carrier mobility than any other material at room temperature. Graphene can therefore be used in applications such as ultrahigh-speed transistors and transparent electrodes. In this paper, we present our preliminary experiments on the transport behavior of graphene at room temperature. We measured the resistivity of Hall-bar samples depending on gate voltage (backgated graphene). Hysteresis between the forward and backward sweep direction was observed.

Summary
Graphene is a very interesting new material that was first prepared by A. S. Novoselov in 2004 [9]. Graphene is a monolayer of a carbon atom in a honeycomb lattice, and can be prepared in various ways. Graphene has very interesting physical behavior, which promises applications in nanodevices such as ultra-high speed transistors and transparent electrodes
