Comment/Description

Graphene is a recently (2004) discovered “two-dimensional” material consisting of a one-atom-thin layer of carbon atoms. In contrast to conventional materials, electrons in graphene have not parabolic but linear energy dispersion and behave like quasi-relativistic massless two-dimensional quasi-particles. This leads to a number of unique electrodynamic properties of graphene, such as its strongly nonlinear electrodynamic and optical response. The linear and nonlinear electrodynamics of graphene is currently intensively studied. An overview of this rapidly developing and hot area of research will be given, with a detailed discussion of fundamental electrodynamic properties of graphene and their possible applications in electronic and optoelectronic devices.
Main topics:
I. Crystal structure and electronic properties of graphene
II. Linear electrodynamics of graphene
1. Linear dynamic conductivity
2. Interaction of electromagnetic waves with graphene
3. Plasma and other electromagnetic waves in graphene
III. Nonlinear electrodynamic properties of graphene
1. Third-order graphene conductivity
2. Overview of different nonlinear effects. Harmonics generation, Kerr effect, four-wave mixing and other
3. Nonlinear effects and plasma waves
4. Hot electron models
