- Abstract
We investigate the transitions between two minibands in a semiconductor superlattice under the influence of high static electric fields. Our numerical calculation, which is based on the two energy levels system, shows that this interminiband transition will lead to anticrossings that can be determined by the coupled Hamiltonian. In the time domain, spatial oscillations come forth between the main locations of the particle in the two transition states. At the anticrossings, the amplitudes are the maximum which agree with the experimental results.
