Abstract
Using the concentration balance equations for each of the main valleys in multivalley semiconductors the relations for valley occupation calculation in high electric field are obtained. In particular, a three-valley model for the conduction band is employed. Analysis of the effect of intervalley momentum relaxation times on valley occupation for both semiconductors GaAs and AlAs was performed basing on the equations mentioned above.
