Abstract

Quantum wells (QWs) have many potential applications, such as laser generators and detectors of infrared signals. Due to the advancement of the molecular beam epitaxy (MBE), a variety of QWs have been fabricated and studied both experimentally and theoretically.
In this report, we study the GaAs/GaAlAs single QW in detail. This type of QW is the most commonly used QW. The energy levels and wave functions are calculated and plotted as functions of the width and depth of the well.
