We present first-principles calculations of the optical response of monolayer molybdenum disulfide employing the GW-Bethe-Salpeter equation (GW-BSE) approach including self-energy, excitonic, and electron-phonon effects. We show that monolayer MoS2 possesses a large and diverse number of strongly bound excitonic states with novel k-space characteristics that were not previously seen experimentally or theoretically. The absorption spectrum is shown to be dominated by excitonic states with a… Expand
A many-body GW + BSE investigation of electronic and optical properties of C2N
A recently synthesized layered material C2N was investigated based on many-body perturbation theory using the GW plus Bethe-Salpeter equation approach. The electronic band gap was determined to beExpand
Quasiparticle energies, excitons, and optical spectra of few-layer black phosphorus
We report first-principles GW?Bethe?Salpeter-equation (BSE) studies of excited-state properties of few-layer black phosphorus (BP) (phosphorene). With improved GW computational methods, we obtainedExpand
Influence of excited carriers on the optical and electronic properties of MoS₂.
TLDR
Study of the ground-state and finite-density optical response of molybdenum disulfide by solving the semiconductor Bloch equations, using ab initio band structures and Coulomb interaction matrix elements reveals a redshift of the excitonic ground- state absorption. Expand
Optoelectronic response and excitonic properties of monolayer MoS2
Ab initio, electronic energy bands of MoS2 single layer are reported within the local density functional approximation. The inclusion of spin orbit coupling reveals the presence of two excitons A andExpand
Temperature Renormalization of Optical Spectra of Monolayer MoS2
Newly measured optical absorption and photoluminescence spectra reveal substantial frequency shifts of both exciton and trion peaks as monolayer MoS2 is cooled from 363 K to 4 K. First-principlesExpand
Optical absorption in monolayer SnO 2
Since the discovery of graphene, considerable research efforts have focused on understanding the properties of other two-dimensional materials. Herein, based on ab initio many-body calculations, weExpand
Exciton Binding Energy of Monolayer WS2
TLDR
An experimental approach to measuring the exciton binding energy of monolayer WS2 with linear differential transmission spectroscopy and two-photon photoluminescence excitation spectroscopic is reported. Expand
Interplay between many body effects and Coulomb screening in the optical bandgap of atomically thin MoS2.
TLDR
Micro-photoluminescence measurements are performed and it is observed that the PL peak redshifts nonlinearly in mono- and bi-layer MoS2 as the excitation power is increased. Expand
Quasiparticle band gaps and optical spectra of strained monolayer transition-metal dichalcogenides
Employing the first-principles many-body perturbation theory, we report the excited-state properties, i.e., quasiparticle energy and excitonic effects, of strained monolayer 2H-phase transition metalExpand
Dielectric screening of excitons and trions in single-layer MoS2.
TLDR
These findings are helpful to better understand the tightly bound exciton properties in strongly quantum-confined systems and provide a simple approach to the selective and separate generation of excitons or trions with potential applications in excitonic interconnects and valleytronics. Expand
