Theory of excitonic complexes in gated WSe$_2$ quantum dots
Single-layer quantum dot gate potential causes type-II band alignment, i.e. electrostatically confines holes and repels electrons, or vice versa. Hence, the confinement of excitons in gated type II quantum dots involves a delicate balance of the repulsion of electrons due to the gate potential with the attraction caused by the …
