Bloch oscillations in superlattices: Monte-Carlo analysis using 2D scattering model

We studied the behavior of Bloch oscillations (BO) in AlGaAs/GaAs superlattices by Monte-Carlo method. Two different scattering models based on effective 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 different conditions such as the intensity of electric field, temperature and ionized impurity density.
