Abstract. Mobility of electrons in multivalley bands of Si and Ge is considered with due
regard for intervalley drag. It is shown that drag sufficiently diminishes electron mobility
at low temperatures. This effect is clearer pronounced in germanium than in silicon.
Keywords: quantum kinetic equation, mobility, intervalley drag.
