Control of excitonic absorption by thickness variation in few-layer GaSe
Arne Budweg, Dinesh Yadav, Alexander Grupp +4
We control the thickness of GaSe on the level of individual layers and study the corresponding optical absorption via highly sensitive differential transmission measurements. Suppr…
Tunability and Losses of Mid-infrared Plasmonics in Heavily Doped Germanium Thin Films
Jacopo Frigerio, Andrea Ballabio, Giovanni Isella +16
Heavily-doped semiconductor films are very promising for application in mid-infrared plasmonic devices because the real part of their dielectric function is negative and broadly tu…
Ultrafast pseudospin dynamics in graphene
M. Trushin, A. Grupp, G. Soavi +8
Interband optical transitions in graphene are subject to pseudospin selection rules. Impulsive excitation with linearly polarized light generates an anisotropic photocarrier occupa…
Tunneling Breakdown of a Strongly Correlated Insulating State in VO Induced by Intense Multi-Terahertz Excitation
B. Mayer, C. Schmidt, A. Grupp +8
We directly trace the near- and mid-infrared transmission change of a VO thin film during an ultrafast insulator-to-metal transition triggered by high-field multi-terahertz tra…
