The impact of intraband carrier dynamics on the optical properties of two-dimensional materials: I. General theory
A. O. Slobodeniuk, T. Novotný
We consider the generation of microscopic polarization in two-dimensional semiconductors under intense optical fields in the non-resonant regime. We demonstrate that the intraband…
Doping-Induced Brightening of Dark Excitons and Trions in a WSe Monolayer
Grzegorz Krasucki, Artur O. Slobodeniuk, Kacper Walczyk +5
Optically dark excitonic states play a critical role in the valleytronic, electronic, and optical properties of monolayer semiconducting transition metal dichalcogenides. Here, we…
High harmonic generation in monolayer MoS2 controlled by resonant and near-resonant pulses on ultrashort time scales
Pavel Peterka, Artur O. Slobodeniuk, Tomáš Novotný +5
We report on experimental investigation of nonperturbative high harmonic generation (HHG) in monolayer MoS2 in the ultraviolet spectral region driven by mid-infrared light. We stud…
Rydberg series of intralayer K-excitons in WSe multilayers
Piotr Kapuscinski, Artur O. Slobodeniuk, Alex Delhomme +6
Semiconducting transition metal dichalcogenides of group VI are well-known for their prominent excitonic effects and the transition from an indirect to a direct band gap when reduc…
