The field dependence of the electron mobility is measured in Te at 77 K using an electron drift technique. In the range up to 80 V/cm the electron mobility is nearly field‐independent. In the range from 100 to 400 V/cm the mobility lowers with E −0.6 . At fields above 600 V/cm only a weak field strength dependence is observed. The zero field mobility ratio of electrons and holes at 77 K is about (3.55 ± 0.25) independently of the hole mobility of the samples.
