Abstract: WOS: 000319490900011<br />In this study, the interband optical transitions and the binding energy of an exciton in a GaAs/Ga1-xAlxAs V-shaped quantum well (VQW) under the electric and magnetic fields are calculated. The calculations were performed within the effective mass approximation, using a variational method. It has been observed that the electric and magnetic fields provide an important effect on the electronic and optical properties in the VQW and the changes in the binding energy depend on the shape of the confinement potential.
