Kapitza-resistance-like exciton dynamics in atomically flat MoSe-WSe lateral heterojunction
Hassan Lamsaadi, Dorian Beret, Ioannis Paradisanos +13
Being able to control the neutral excitonic flux is a mandatory step for the development of future room-temperature two-dimensional excitonic devices. Semiconducting Monolayer Tran…
Control of the Bright-Dark Exciton Splitting using Lamb Shift in a 2D Semiconductor
L. Ren, C. Robert, M. M. Glazov +7
We have investigated the exciton fine structure in atomically thin WSe2 -based van der Waals heterostructures where the density of optical modes at the location of the semiconducto…
Optical manipulation of the Rashba effect in germanium quantum wells
S. Rossi, E. Talamas Simola, M. Raimondo +6
The Rashba effect in Ge/SiGe multiple quantum wells embedded in a p-i-n diode is studied through polarization and time-resolved photoluminescence. In addition to…
Intervalley electron-hole exchange interaction and impurity-assisted recombination of indirect excitons in WS and WSe monolayers
Pengke Li, Cedric Robert, Dinh Van Tuan +3
The variety of excitonic states in tungsten-based dichalcogenide monolayers stems from unique interplay between the spin and valley degrees of freedom. One of the exciton species i…
Valley polarization fluctuations, bistability, and switching in two-dimensional semiconductors
M. A. Semina, M. M. Glazov, C. Robert +3
We study theoretically nonlinear valley polarization dynamics of excitons in atom-thin semiconductors. The presence of significant polarization slows down valley relaxation due to…
Second harmonic generation control in twisted bilayers of transition metal dichalcogenides
Ioannis Paradisanos, Andres Manuel Saiz Raven, Thierry Amand +7
The twist angle in transition metal dichalcogenide (TMD) heterobilayers is a compelling degree of freedom that determines electron correlations and the period of lateral confinemen…
