Dear all,

   Hi I am trying to calculate the electron-phonon interaction matrix
element for semiconductors, as described in the documentation as g(k,i,j)  :


  The expression for g(k,i,j) is generic and should apply to both
semiconductors and metals (correct?). But why does is also say in the
documentation that only calculations for METALS are allowed? To further
calculate the phonon linewidth? If that is true then can we do calculations
for semiconductors and extract the matrix element from the output? I need
those to calculate phonon-limited carrier mobility. Thanks in adance!
