Recent experiments on hot electron spectrometers in n doped GaAs have produced pathlengths in the range 300 to 500 Å at 77 K for hot electron decay. The scattering has been attributed to electron-electron and electron-phonon interaction. The authors have made a detailed theoretical study of these effects in GaAs in the doping range n=1017/1018 cm-3 where polar LO phonon and plasmon mode mixing effects are expected to be greatest. Dispersion in the initial unmixed plasmon mode, mode mixing effects causing altered dispersion and dynamical screening by the electrons and phonons are all found to influence the damping of hot electrons. In particular for the plasmon frequency
