$negfintervalleyopticalphonon

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

$W_{pop}^{ab}(k)=\frac{|C|^2V}{4\pi^2\hbar^2}[n(\omega_{0})]N_{1D}(E_{k}+\hbar\omega_{0})$

$W_{pop}^{em}(k)=\frac{|C|^2V}{4\pi^2\hbar^2}[n(\omega_{0}+1)]N_{1D}(E_{k}-\hbar\omega_{0})$

$C=i\sqrt{\frac{e^{2}\hbar\omega_{0}}{2\epsilon_{0}V}(\frac{1}{\epsilon_{\infty}}-\frac{1}{\epsilon_{s}})}$
