Some notable experiments of graphene

Abstract

Graphene is an allotrope of carbon where carbon atoms are attached through sp2 hybridization in a two-dimensional (2D) plane. Based on the structure, graphene can be visualized as a single sheet of graphite. A. Geim and K. Novoselov successfully isolated free standing monolayer graphene from graphite by scotch tape method for the first time in 2004. This discovery won them the Nobel Prize in physics 2010. However, several inception experiments had been carried out much before its birth by other eminent scientists. In fact, several extended experiments have been performed to understand the properties of graphene after its discovery. This article is a collection of some of the notable pre and post-discovery experiments. In addition, it includes some of the experiments those have been carried out at CSIR-NML.
