✦ Synopsis


We studied the behavior of Bloch oscillations (BO) in AlGaAs/GaAs superlattices by Monte-Carlo method. Two di erent scattering models based on e ective mass approximation were used for studying of electron miniband transport. Scattering on polar optical and acoustic phonons as well as impurities were taken into account. Behavior of BO was studied under di erent conditions such as the intensity of electric ΓΏeld, temperature and ionized impurity density.
