摘要:
It is suggested that a perpendicular magnetic field can strongly suppress the most important nonradiative intersubband transition processes, namely Auger recombination and optical phonon transitions, in an intersubband infrared laser device that has recently been proposed using multiple quantum wells. The present analysis suggests that the fabrication of such a novel laser device is quite realistic using present III‐V technologies.
