Abstract

The idea of the present research project is to continue and extend the experimental and theoretical study of the fundamental transport properties of Graphene, multilayer graphene and graphite. In particular we will focus on the effects induced by non- linear interactions and disorder, and their influence on transport. Also we are interested in the quantum phases transitions (localization-delocalization) associated with the quantum hall plateaus in these materials to increase our understanding of the transition for a pure 2D material as graphene to a quasi-2D material as graphite. These results can provide key information for the design of new graphene/graphite-based electronic devices. Hence, the objective of our ongoing work is two-fold: (i) optimize physical properties of graphene/graphite and (ii) functionalize the graphene/graphite, viz. add new functions, features, capabilities to this material making it semicondutor.
