Mass Renormalization in Transition Metal Dichalcogenides
T. Stroucken, J. Neuhaus, S. W. Koch
It is shown that the three-fold rotational symmetry in transition metal dichalcogenides leads to a Coulomb induced renormalization of the effective electron and hole masses near th…
Spin-Layer- and Spin-Valley-Locking in CVD-Grown AA'- and AB-Stacked Tungsten-Disulfide Bilayers
Lorenz Maximilian Schneider, Jan Kuhnert, Simon Schmitt +10
Valley-selective optical selection rules and a spin-valley locking in transition-metal dichalcogenide (TMDC) monolayers are at the heart of "valleytronic physics", which exploits t…
Ultrafast band-gap renormalization and build-up of optical gain in monolayer MoTe
Lars Meckbach, Jörg Hader, Josefine Neuhaus +5
The dynamics of band-gap renormalization and gain build-up in monolayer MoTe is investigated by evaluating the non-equilibrium Dirac-Bloch equations with the incoherent carrier…
Superradiant coupling effects in transition-metal dichalcogenides
C. E. Stevens, T. Stroucken, A. V. Stier +6
Cooperative effects allow for fascinating characteristics in light-matter interacting systems. Here, we study naturally occurring superradiant coupling in a class of quasi-two-dime…
Influence of the effective layer thickness on the groundstate and excitonic properties of transition-metal dichalcogenide systems
Lars Meckbach, Tineke Stroucken, Stephan W. Koch
A self-consistent scheme for the calculations of the interacting groundstate and the near bandgap optical spectra of mono- and multilayer transition-metal-dichalcogenide systems is…
Screening and gap generation in bilayer graphene
Tineke Stroucken, Johanna H. Grönqvist, Stephan. W. Koch
A fully selfconsistent treatment for gap generation and Coulomb screening in excitonic insulators is presented. The method is based on the equations of motion for the relevant dyna…
