Electron Motion in Graphene

Abstract

Dr. Chun Wang*

In this paper, I propose a new electronic structure of graphene and theoretically reinterpret the results of several well- known experiments. Based on the material’s electrical neutrality, each carbon atom on the graphene hexagonal network should have one unpaired electron. When a stable monolayer is formed, the two unpaired electrons from two adjacent carbon atoms rearrange in elliptical π-orbits above and below the layer revolving around two carbon atoms, just like unpaired electrons in a double bond. The electronic structure of graphene consists of alternating double and single bonds. Graphene, like graphite, is diamagnetic due to the close arrangement of unpaired electrons.

These unpaired electron orbits form two layers of electron gas. The lateral drift of electron orbits under a perpendicular magnetic field exhibits the quantum Hall effect in graphene, as is the case in two-dimensional electron gas system. The superconductivity of light-irradiated monolayer, calcium-intercalated bilayer, twisted bilayer, and trilayer of graphene can all be traced to the contact of unpaired electron orbits.
