In this Mini Review, we summarize major corrections to the dark–bright exciton theory [Efros et al. Phys. Rev B 1996, 54, 4843− 4856], which should be used for quantitative description …
Excitons, Coulomb-bound electron–hole pairs, are elementary photo-excitations in semiconductors that can couple to light through radiative relaxation. In contrast, dark …
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 …
We demonstrate that the quantum dot-confined dark exciton forms a long-lived integer spin solid-state qubit that can be deterministically on-demand initiated in a pure state by one …
We analyze theoretically physical mechanisms responsible for the radiative recombination of the ground optically passive (“dark”) exciton (DE), which dominates in photoluminescence …
We use an atomistic model to consider the effect of shape symmetry breaking on the optical properties of self-assembled InAs/GaAs quantum dots. In particular, we investigate the …
We present atomistic theory of emission from dark excitons in self-assembled quantum dots. Using the atomistic tight-binding model coupled with the configuration-interaction approach …
We present a micropillar cavity where nondesired radial emission is inhibited. The photonic confinement in such a structure is improved by implementation of an additional concentric …
We use one single, few-picosecond-long, variably polarized laser pulse to deterministically write any selected spin state of a quantum dot confined dark exciton whose life and …
