Abstract :
Summary form only given. Carrier tunneling in semiconductor heterostructures has been a topic of research interest because of its fundamental and applied aspects. Exciton binding energy in wide-gap II-VI semiconductors is relatively large; thus their tunneling structures are ideal to study the influence of excitonic effects on the tunneling process. Here we report a time resolved investigation of exciton tunneling in a ZnCdSe-ZnSe asymmetric double quantum well (ADQW) structure.
