Electron dynamics in graphene with gate-defined quantum dots
A. Pieper, R. L. Heinisch, H. Fehske
We use numerically exact Chebyshev expansion and kernel polynomial methods to study transport through circular graphene quantum dots in the framework of a tight-binding honeycomb l…
Optical signatures of the Charge of a Dielectric Particle in a Plasma
R. L. Heinisch, F. X. Bronold, H. Fehske
With an eye on dust particles immersed into an ionized gas, we study the effect of a negative charge on the scattering of light by a dielectric particle with a strong transverse op…
Surface electrons at plasma walls
Rafael L. Heinisch, Franz X. Bronold, Holger Fehske
In this chapter we introduce a microscopic modelling of the surplus electrons on the plasma wall which complements the classical description of the plasma sheath. First we introduc…
Mie scattering analog in graphene: lensing, particle confinement, and depletion of Klein tunneling
R. L. Heinisch, F. X. Bronold, H. Fehske
Guided by the analogy to Mie scattering of light on small particles we show that the propagation of a Dirac-electron wave in graphene can be manipulated by a circular gated region…
