Abstract
We study electron–hole exchange interaction in a single CdTe/ZnTe quantum dot by polarization-resolved photoluminescence measurements. We focus on recombination of excitonic states involving p-shell electrons: X2− and XX−. Recombination lines of X2− and XX− states exhibit fine structure, which can be consistently explained within a model with four parameters δ i representing strength of isoand anisotropic parts of interaction between s-hole and sor p-electron.
