Relaxation and darkening of excitonic complexes in electrostatically-doped monolayer semiconductors: Roles of exciton-electron and trion-electron interactions
Min Yang, Lei Ren, Cedric Robert +5
We present photoluminescence measurements in monolayer WSe, which point to the importance of the interaction between charged particles and excitonic complexes. The theoretical…
Impact of excitation energy on hot carrier properties in InGaAs MQW structure
Hamidreza Esmaielpour, Laurent Lombez, Maxime Giteau +2
Hot carrier solar cells aim to overcome the theoretical limit of single-junction photovoltaic devices by suppressing the thermalization of hot carriers and extracting them through…
Imaging Seebeck drift of excitons and trions in MoSe2 monolayers
Sangjun Park, Bo Han, Caroline Boule +10
Hyperspectral imaging at cryogenic temperatures is used to investigate exciton and trion propagation in MoSe monolayers encapsulated with hexagonal boron nitride (hBN). Under a…
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…
Interlayer exciton mediated second harmonic generation in bilayer MoS2
Shivangi Shree, Delphine Lagarde, Laurent Lombez +10
Second harmonic generation (SHG) is a non-linear optical process, where two photons coherently combine into one photon of twice their energy. Efficient SHG occurs for crystals with…
