Tunnelling of spin-polarized holes in asymmetric double quantum well structures

We report on time-resolved photoluminescence studies of tunnelling in a system of asymmetric double quantum wells (QWs). We employ a structure with a semimagnetic QW to align carrier spins and with excess concentration of electrons to provide a sensitive tool for studying the heavy hole dynamics. We prove the existence of hole tunnelling and demonstrate an efficient spin transfer in the process. A semi-empirical model describes qualitatively the experimental findings.
