Abstract
The velocity autocorrelation (t) function is calculated for electrons moving along a high electric field in n-type silicon. For short times t, it varies as exp(-t0), but for times greater than approximately 1.50, the short-time exponential decay appears to go over to a t-32 decay. This representation covers the initial relaxation, but a second exponential also appears as relaxation to the nonequilibrium steady state occurs.
