Ambipolar metal-insulator transition in bilayer MoSe2
Ha-Leem Kim, Hyungbin Lim, Terry Wu +7
When Coulomb interactions dominate kinetic energy, dilute two-dimensional carriers form a Wigner solid. Both its melting and disorder-driven localization can drive density-tuned me…
Confined exciton polaron in MoS on twisted-hBN
Garima Gupta, Mayank Chhaperwal, Pankaj Kumar +5
The simple electrostatic picture of a trion is that of an excess charge inducing an exciton polarization and binding closer (farther) to the hole (electron) side of it. Trion forma…
Motion of 2D exciton in momentum space leads to pseudospin distribution narrowing on the Bloch Sphere
Garima Gupta, Kenji Watanabe, Takashi Taniguchi +1
Motional narrowing implies narrowing induced by motion, for example, in nuclear resonance, the thermally induced random motion of the nuclei in an inhomogeneous environment leads t…
Polarized and narrow excitonic emission from graphene-capped monolayer WS through resonant phonon relaxation
Garima Gupta, Kausik Majumdar
The broadening and polarization of excitonic luminescence in monolayer TMDs largely suffer from inhomogeneity and temperature - an unresolved problem to date. In this work, through…
Highly nonlinear biexcitonic photocurrent from ultrafast inter-layer charge transfer
Sarthak Das, Garima Gupta, Suman Chatterjee +3
Strong Coulomb interaction in monolayer semiconductors allows them to host optically active large many-body states, such as the five-particle state, charged biexciton. Strong nonli…
Trion-trion annihilation in monolayer WS
Suman Chatterjee, Garima Gupta, Sarthak Das +3
Strong Coulomb interaction in monolayer transition metal dichalcogenides can facilitate nontrivial many-body effects among excitonic complexes. Many-body effects like exciton-excit…
