QUANTUM TRANSPORT IN GRAPHENE: MECHANISMS AND DEVICE APPLICATIONS

Abstract

Graphene, a monolayer of carbon atoms arranged in a hexagonal lattice, exhibits exceptional electronic properties, including high carrier mobility, ambipolar conduction, and ballistic transport over submicron distances. These unique quantum transport characteristics make graphene a promising material for next-generation nanoelectronic and optoelectronic devices. This paper reviews the fundamental mechanisms of charge transport in graphene, examines the effects of scattering and substrate interactions, and explores recent advancements in graphene-based electronic devices. The challenges and future prospects of integrating graphene into practical systems are discussed.
