Graphene carriers moblility study in nanoscale: application of Monte Carlo method

Abstract

Graphene atoms are arranged horizontally structured perfectly. With mechanical and electrical distinguished by their ability to remain on the structure of carbon arranged in one atomic layer in two-dimensional. Graphene is capable of bringing electricity better than copper four times and the surface area of more than two times stronger than steel, carbon nanotubes 200 times stronger than diamond. Flexible and translucent allowing light to pass through up to 97 percent are interesting for basic education and deployment in the future. It can be used to produce graphene actually succeed in bringing sheets of graphene as transparent conductor that can be used in devices such as touch screens solar cell. It can be used to replace the production of solar cells by replacing indium tin oxide which expensive material. Since this material graphene has an important role in the creation of display devices such as LCD, capacitor, battery and solar cell, which describes the movement of the carrier in the lattice can be very difficult by traditional model. Hopping model is the new model to describe carrier transport that to know the carrier mechanism. it is important characteristics of graphene to applied effectively.
