Abstract :
The energy distribution of hot electrons quasiballistically injected in p+ GaAs has been probed directly using the tunnelling resonances of a double barrier in a specially designed two-terminal heterojunction device. The photocurrent/voltage characteristics give direct information on the hot electron spectrum, without requiring derivative techniques.
