$negfintervalleyopticalphonon

$negfintervalleyopticalphonon is the command to setup the related parameters of intervally optical phonon scattering.

$W_{pop}^{ab}(k)=\frac{|C{|}^{2}V}{4{\pi }^2{\hslash }^2}[n({\omega }_0)]N_{1D}(E_k+\hslash {\omega }_0)$

$W_{pop}^{em}(k)=\frac{|C{|}^{2}V}{4{\pi }^2{\hslash }^2}[n({\omega }_0+1)]N_{1D}(E_k-\hslash {\omega }_0)$

$C=i\sqrt{\frac{e^2\hslash {\omega }_0}{2{ϵ}_{0}V}(\frac{1}{{ϵ}_{\mathrm{\infty }}}-\frac{1}{{ϵ}_s})}$
