$negfacousticphonon is the command to setup the related parameters of acoustic phonon scattering. You can also use this function and set the parameter with our GUI version at the place of "Scattering Parameters" in GUI<br>
The equation of acoustic phonon scattering:
 <math>W_{ac}(k)=\frac{2\pi k_{B}T}{\hbar\rho\nu_{ac}^{2}}D_{ac}I_{if}N_{1D}(E_{k})</math><br>

 $negfacousticphonon
 <math>D_{ac}</math> <math>\nu_{ac}</math><br>
