Working Group Theory of Graphene and Related Nanostructures


Head: Prof. Dr. Igor Gornyi

We study transport in graphene structures, including conductivity for different types of scatterers, quantum interference phenomena, transport regimes (ballistics, localization, diffusion, criticality), interaction effects, and non-equilibrium physics.

In particular, we investigate:

  • Influence of electron-phonon coupling on elastic properties of graphene bilayers and monolayers
  • Strongly nonequilibrium graphene, relaxation of hot carriers
  • Double-layer graphene (Coulomb drag)
  • Transport and spectral properties of graphene with strong scatterers

Other research topics

Ballistic graphene setup with various strong scatterers
Coulomb drag in graphene
