Abstract
We propose a test whereby the intervalley transfer of electrons in semiconductors under the influence of a high electric field can be determined. The same experiment can be used also to determine the electron temperature. The present test is based on the fact that as the transfer occurs, the plasma frequency of the electrons undergoes an appreciable change because the masses of the different valleys differ considerably.Keywords
