The bright emission observed in cesium lead halide perovskite nanocrystals (NCs) has recently been explained in terms of a bright exciton ground state [Becker et al. Nature 2018, 553, 189−193], a claim that would make these materials the first know

Several important proposals to use semiconductor quantum dots in quantum information technology rely on the control of the dark exciton ground states, such as dark exciton based qubits with a $\mu$s life time. In this paper, we present an efficient w

International audience; Time-resolved measurements of the exciton dynamics in tungsten diselenide monolayers reveal ultrafast radiative recombination of the exciton ground state (∼150 fs) and the interplay between optically bright and dark excitons

Taking into account the tetrahedral shape of a quantum dot quantum well (QDQW) when describing excitonic states, phonon modes and the exciton-phonon interaction in the structure, we obtain within a non-adiabatic approach a quantitative interpretation

Basing on the Green's function method for the study of disordered systems, we propose a simple model that describes the shift and broadening of excitonic resonance in interface-corrugated quantum wells. This model employs the original microscopic exc

The effects of discontinuities of the material parameters at the interfaces of narrow GaAs-based quantum wells as well as of the nonparabolicity of the conduction band on the exciton binding energy are studied. These effects are taken into account in

Exciton spectra in bulk semiconductor in strong magnetic fields were studied in the two-band Dirac model. An expression for the energy of ortho-para splitting of the ground state was derived.
