A Note on the Measurement of the Intersubband Relaxation Time by an Infrared Bleaching Technique
The investigation and analysis of electron intersubband transitions within quantum wells (QWs) and multiple quantum well structures (MQWSs) is an important aspect since the successful operation of many proposed electro-optical devices depends on these processes. In particular, the intersubband relaxation time determines to a large degree on the sensitivity of infrared detectors based on intersubband optical absorption.
