We carried out electroreflectance measurements in a CaAs/AJGaAs superlatice at is \(\mathrm{K}\) in order to investigate the resonant couplings between the Stark-ladder states. The experimental data are analyzed by using tight-binding theory, including the electric field effect. From the comparison
In the framework of regular perturbation theory we discuss the weak field crossing behavior of the resonances in double ladder (and double well) Stark problems. We get a precise condition for the anticrossing in terms of the Agmon length of the Zener barriers. This condition has a simple physical me
