Scattering of two-dimensional Dirac fermions on gate-defined oscillating quantum dots
C. Schulz, R. L. Heinisch, H. Fehske
Within an effective Dirac-Weyl theory we solve the scattering problem for massless chiral fermions impinging on a cylindrical time-dependent potential barrier. The set-up we consid…

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…
