Non-Degenerate Two-Photon Absorption in ZnSe: Experiment and Theory
L. Krauss-Kodytek, W. -R. Hannes, T. Meier +2
We experimentally and theoretically investigate the non-degenerate two-photon absorption coefficient in the prototypical semiconductor ZnSe. In particular, we provide…
Higher-order contributions and non-perturbative effects in the non-degenerate nonlinear optical absorption of direct-gap semiconductors
W. -R. Hannes, T. Meier
The semiconductor Bloch equations for a two-band model including inter- and intraband excitation are used to study the nonlinear absorption of single and multiple light pulses by d…
Electron-hole asymmetry in two-terminal graphene devices
W. -R. Hannes, M. Jonson, M. Titov
A theoretical model is proposed to describe asymmetric gate-voltage dependence of conductance and noise in two-terminal ballistic graphene devices. The model is analyzed independen…
Ballistic charge transport in chiral-symmetric few-layer graphene
W. -R. Hannes, M. Titov
A transfer matrix approach to study ballistic charge transport in few-layer graphene with chiral-symmetric stacking configurations is developed. We demonstrate that the chiral symm…
