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…
Interface engineering of charge-transfer excitons in 2D lateral heterostructures
Roberto Rosati, Ioannis Paradisanos, Libai Huang +9
The existence of bound charge transfer (CT) excitons at the interface of monolayer lateral heterojunctions has been debated in literature, but contrary to the case of interlayer ex…
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…
Spin/Valley pumping of resident electrons in WSe2 and WS2 monolayers
Cedric Robert, Sangjun Park, Fabian Cadiz +14
Monolayers of transition metal dichalcogenides are ideal materials to control both spin and valley degrees of freedom either electrically or optically. Nevertheless, optical excita…
Wide range electrical tunability of single photon emission from chromium-based colour centres in diamond
T. Müller, I. Aharonovich, L. Lombez +7
We demonstrate electrical control of the single photon emission spectrum from chromium-based colour centres implanted in monolithic diamond. Under an external electric field the tu…
