Abstract: Energy levels and wavefunctions in GaAs quantum wells are calculated by solving the Schrdinger equation using Numerov method, and their dependence on various parameters including well width, barrier height and external field are examined in detail. The obtained results are useful in study of electro-optic properties of GaAs/AlGaAs quantum well structures and the device design. -
