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:
$negfpolaropticalphonon
Example:
$negfpolaropticalphonon 5320.0 10.92 13.2 1.60e-8 5.18e13
related commands:
$ifsolvenegf, $negfifscattering
