Competition Between Tunneling and Exciton Formation for Photoexcited Carriers in Asymmetric Double Wells,

Abstract

The formation of excitons from photoexcited free carriers in a GaAs asymmetric double quantum well tunneling structure is shown to occur by a bimolecular process. Using the non-linear luminescence cross-correlation technique, a bi-molecular formation coefficient of 6xlO-12cm2/ps is determined. The electron and hole tunneling times are also simultaneously obtained.
