Efficient valley polarization of charged excitons and resident carriers in MoS2 monolayers by optical pumping
Sangjun Park, Steve Arscott, Takashi Taniguchi +3
We investigate with polarized microphotoluminescence the optical pumping of the valley degree of freedom in charge-tunable MoS2 monolayers encapsulated with hexagonal boron nitride…
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…
Subpicosecond metamagnetic phase transition driven by non-equilibrium electron dynamics
Federico Pressacco, Davide Sangalli, Vojtěch Uhlíř +13
Femtosecond light-induced phase transitions between different macroscopic orders provide the possibility to tune the functional properties of condensed matter on ultrafast timescal…
