Ultra-broadband bright light emission from a one-dimensional inorganic van der Waals material
Fateme Mahdikhany, Sean Driskill, Jeremy G. Philbrick +10
One-dimensional (1D) van der Waals materials have emerged as an intriguing playground to explore novel electronic and optical effects. We report on inorganic one-dimensional SbPS4…
Dynamical Control of Interlayer Excitons and Trions in WSe/MoWSe Heterobilayer via Tunable Near-Field Cavity
Yeonjeong Koo, Hyeongwoo Lee, Tatiana Ivanova +5
Emerging photo-induced excitonic processes in transition metal dichalcogenide (TMD) heterobilayers, e.g., coupling, dephasing, and energy transfer of intra- and inter-layer exciton…
Nonlinear spectroscopy of excitonic states in transition metal dichalcogenides
Yaroslav V. Zhumagulov, Vyacheslav D. Neverov, Alexander E. Lukyanov +4
Second-harmonic generation (SHG) is a well-known nonlinear spectroscopy method to probe electronic structure, specifically, in transition metal dichalcogenide (TMDC) monolayers. Th…
Simulation of Scanning Near-Field Optical Microscopy Spectra of 1D Plasmonic Graphene Junctions
Vyacheslav Semenenko, Mengkun Liu, Vasili Perebeinos
We present numerical simulations of scattering-type Scanning Near-Field Optical Microscopy (s-SNOM) of 1D plasmonic graphene junctions. A comprehensive analysis of simulated s-SNOM…
Microscopic theory of exciton and trion polaritons in doped monolayers of transition metal dichalcogenides
Y. V. Zhumagulov, S. Chiavazzo, D. R. Gulevich +3
We study a doped transition metal dichalcogenide (TMDC) monolayer in an optical microcavity. Using the microscopic theory, we simulate spectra of quasiparticles emerging due to the…
Electrostatic control of the trion fine structure in transition metal dichalcogenide monolayers
Yaroslav V. Zhumagulov, Alexei Vagov, Dmitry R. Gulevich +1
Charged excitons (trions) are essential for the optical spectra in low dimensional doped monolayers (ML) of transitional metal dichalcogenides (TMDC). Using a direct diagonalizatio…
