Abstract
The effect of an electric field on the energy spectrum of a quantum well with macroscopic fluctuations is studied. The Stark shift of the quasibound states in a quantum well and three field-dependent broadening mechanisms (field-induced homogeneous broadening and broadening due to well width and depth fluctuations) are calculated in a wide range of electric fields. As an example, the effect of an electric field on the energy spectrum of electrons in a 12-nm-wide GaAs/Al0.3Ga0.7As quantum well with 5% width and depth fluctuations is determined.
