Dear all, I'm trying to calculate the electron-phonon absorption/emission scattering rate in a graphene sheet. I tried to extrapolate the value of the transition matrix element for each k ---> k+q transition, to be integrated as a function of q in order to obtain the scattering rate. I'm not able to understand the measure unit of the transition matrix element, as it is calculated from elphel subroutine. Any hint would be welcome.
Thanks Samantha
