$negfsurfaceroughness is the command to setup the related parameters of surface roughness scattering.
The equation of surface roughness scattering:
![W_{sr}(k)=\frac{2\pi}{\hbar}\{\frac{2U_{0}I_{if}f(\Delta)\sin[(k_{i}-k_{f})]\frac{\lambda}{2}}{k_{i}-k_{f}}\}^{2}\frac{N_{1D}(E_{k})}{\sigma}](/mediawiki/images/math/3/7/6/37609ec39c9ed8d28fda43e1aed32f28.png)
Example:
$negfsurfaceroughness
$negfsurfaceroughness 2.0e-9 7.328e-19 #colength U0
related commands:
