Abstract:

Spins of resident holes in charged quantum dots QDs act as local magnets inducing Zeeman splitting of excitons trapped into dots. This has been evidenced by observation of quantum beats in linearly polarized time-resolved photoluminescence of a biased array of self-assembled InP QDs. A theory is developed that considers the exchange interaction within the positively charged exciton trion states formed in the QD.
