Spin-Valley Relaxation of Rydberg Excitons
V. Jindal, K. Mourzidis, M. Semina +8
Rydberg excitons, characterized by large spatial extension and reduced electron-hole overlap, must have a spin-valley dynamics different from that of ground state excitons. Here we…
Exciton Formation in Two-Dimensional Semiconductors
K. Mourzidis, V. Jindal, M. Glazov +10
The optical properties of atomically thin semiconductors are dominated by excitons, tightly bound electron-hole pairs, which give rise to particularly rich and remarkable physics.…
Excited-State Trions in a Quantum Well
Sourabh Jain, Mikhail Glazov, Ashish Arora
We report on the observation of an excited 2s state of a trion in a 4.2 nm wide doped GaAs/Al(0.3)Ga(0.7)As quantum well (QW) using magneto-optical Kerr effect (MOKE) spectroscopy…
Spin-valley polarization control in WSe monolayers using photochemical doping
E. Katsipoulaki, K. Mourzidis, V. Jindal +9
We report on the influence of a photochemical doping method on the spin-valley polarization degree () of excitons in WSe monolayers. By varying the carrier density and t…
