If you use the command $negfifscattering and the second term is 1, then use the command $negfpolaropticalphonon to setup the related parameters of polar optical phonon scattering of GaAs.
The equation of polar optical phonon scattering:

Wpopab(k)=|C|2V4π22[n(ω0)]N1D(Ek+ω0)
Wpopem(k)=|C|2V4π22[n(ω0+1)]N1D(Ekω0)
C=ie2ω02ϵ0V(1ϵ1ϵs)
$negfpolaropticalphonon
ρ  ϵ  ϵs
Dop ω0

Example:

$negfpolaropticalphonon
