Optical spectroscopy of excited exciton states in MoS2 monolayers in van der Waals heterostructures
C. Robert, M. A. Semina, F. Cadiz +12
The optical properties of MoS2 monolayers are dominated by excitons, but for spectrally broad optical transitions in monolayers exfoliated directly onto SiO2 substrates detailed in…
Carrier and Spin Coherent Dynamics in Strained Germanium-Tin Semiconductor on Silicon
Sebastiano De Cesari, Andrea Balocchi, Elisa Vitiello +6
Germanium-Tin is emerging as a material exhibiting excellent photonic properties. Here we demonstrate optical initialization and readout of spins in this intriguing group IV semico…
Fine Structure and Lifetime of Dark Excitons in Transition Metal Dichalcogenide Monolayers
Cedric Robert, Thierry Amand, Fabian Cadiz +7
The intricate interplay between optically dark and bright excitons governs the light-matter interaction in transition metal dichalcogenide monolayers. We have performed a detailed…
Synthesis of Highly Anisotropic Semiconducting GaTe Nanomaterials and Emerging Properties Enabled by Epitaxy
Hui Cai, Bin Chen, Gang Wang +7
Pseudo-one dimensional (pseudo-1D) materials are a new-class of materials where atoms are arranged in chain like structures in two-dimensions (2D). Examples include recently discov…
In-plane Propagation of Light in Transition Metal Dichalcogenide Monolayers: Optical Selection Rules
G. Wang, C. Robert, M. M. Glazov +8
The optical selection rules for inter-band transitions in WSe2, WS2 and MoSe2 transition metal dichalcogenide monolayers are investigated by polarization-resolved photoluminescence…
Excitonic linewidth approaching the homogeneous limit in MoS2 based van der Waals heterostructures : accessing spin-valley dynamics
F. Cadiz, E. Courtade, C. Robert +13
The strong light matter interaction and the valley selective optical selection rules make monolayer (ML) MoS2 an exciting 2D material for fundamental physics and optoelectronics ap…
