J. Kuhl et al., TUNNELING OF ELECTRONS AND HOLES IN ASYMMETRIC DOUBLE QUANTUM-WELL STRUCTURES, Semiconductor science and technology, 7(3B), 1992, pp. 418-420
Simultaneous measurements of electron and hole tunnelling times, and t
he exciton formation rate in asymmetric double quantum well structures
are achieved by the nonlinear double-pulse photoluminescence cross-co
rrelation technique.
