摘要：
Femtosecond optical pulses of 14 fs duration were used to investigate exciton dynamics in II-VI CdZnTe-ZnTe multiple quantum wells at room temperature. An exciton ionization time of 110 fs has been determined. These are the first reported experiments on femtosecond dynamics in II-VI quantum wells. The bleaching effect of "cold" neutral excitons on excitons has been compared to that from the same density of "cool" free electron-hole pairs.
