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
The current-voltage characteristic of a semiconductor superlattice in the Stark ladder regime has been calculated. It is shown that the negative differential conductivity onset electric field is defined by the scattering time, which depends only very slightly on the superlattice miniband width.
