Abstract
It is shown theoretically that the average drift velocity of electrons in GaAs as measured by microwave techniques differs substantially from the dc characteristic. This error, arising from electron‐energy relaxation effects, has always been neglected in past measurements. The simple model predicts an error of 16% in measured velocity at 35 GHzKeywords
