Excitonic effects play a particularly important role in the optoelectronic behavior of two dimensional semiconductors. To facilitate the interpretation of experimental photoabsorption and photoluminescence spectra we provide (i) statistically exact diffusion quantum Monte Carlo bindingenergy data for a Mott-Wannier model of (donor/acceptor-bound) excitons, trions, and biexcitons in two-dimensional semiconductors in which charges interact via the Keldysh potential, (ii) contact pair-distribution… 

Charge-tuneable biexciton complexes in monolayer WSe2

Experimental evidence of four- and five-particle biexciton complexes in monolayer WSe2 and their electrical control are reported and offer direct routes towards deterministic control in many-body quantum phenomena.

Dynamical screening in monolayer transition-metal dichalcogenides and its manifestations in the exciton spectrum

A systematic description of the dynamical screening and its various approximations allow one to revisit other phenomena, such as nonequilibrium transport or superconducting pairing, where the use of the Bethe-Salpeter equation or the emergence of shortwave plasmons can play an important role.

Dynamical Screening of Excitons in Monolayer Transition-Metal Dichalcogenides

We review the manifestations of many-body interactions in monolayer transition-metal dichalcogenides (ML-TMDs) through changes in the optical spectra of excitons when the charge density is varied

Coulomb-bound four- and five-particle intervalley states in an atomically-thin semiconductor

Experimental evidence is presented for four-particle biexcitons and five- particle exciton-trions in high-quality monolayer tungsten diselenide that are bound with respect to the bright exciton and the trion and intervalley complexes involving dark excitons.

A first-principles Quantum Monte Carlo study of two-dimensional (2D) GaSe.

It is confirmed that monolayer GaSe is an indirect gap semiconductor with a quasiparticle electronic gap in close agreement with experiment and low exciton binding energy and the optimal lattice parameter, cohesive energy, and ground state charge density with DMC and various DFT methods.

Localization-induced optical properties of monolayer transition-metal dichalcogenides

Impurities play an important role during recombination processes in semiconductors. Their important role is sharpened in atomically-thin transition-metal dichalcogenides whose two-dimensional

Coulomb interaction in monolayer transition-metal dichalcogenides

Recently, the celebrated Keldysh potential has been widely used to describe the Coulomb interaction of few-body complexes in monolayer transition-metal dichalcogenides. Using this potential to model

Ab initio modelling of two-dimensional semiconductors

We study excited-state phenomena in a variety of semiconductor systems, with use of the variational and diffusion quantum Monte Carlo (QMC) methods. Firstly, we consider the formation of

Exciton-Scattering-Induced Dephasing in Two-Dimensional Semiconductors.

Enhanced Coulomb interactions in monolayer transition metal dichalcogenides cause tightly bound electron-hole pairs (excitons) that dominate their linear and nonlinear optical response. The latter

Symmetry-dependent exciton-exciton interaction and intervalley biexciton in monolayer transition metal dichalcogenides

The multivalley band structure of monolayer transition metal dichalcogenides (TMDs) gives rise to intravalley and intervalley excitons. Much knowledge of these excitons has been gained, but
