Electron flow in circular graphene quantum dots
C. Schulz, R. L. Heinisch, H. Fehske
We study the electron propagation in a circular electrostatically defined quantum dot in graphene. Solving the scattering problem for a plane Dirac electron wave we identify differ…
Dot-bound and dispersive states in graphene quantum dot superlattices
A. Pieper, R. L. Heinisch, G. Wellein +1
We consider a square lattice configuration of circular gate-defined quantum dots in an unbiased graphene sheet and calculate the electronic, particularly spectral properties of fin…
Infrared light extinction by charged dielectric core-coat particles
Elena Thiessen, Rafael L. Heinisch, Franz X. Bronold +1
We study the effect of surplus electrons on the infrared extinction of dielectric particles with a core-coat structure and propose to use it for an optical measurement of the parti…
