    • It is worth pointing out that our assignment of the (Equation presented)-point phonon for (Equation presented) is similar to that for (Equation presented) by Berkdemir [41], but in our case is based on a different intervalley process. Berkdemir [41] used a laser line (514.5 nm) which matches the (Equation presented)-point gap of (Equation presented) and therefore may trigger an intervalley electron-phonon process between the (Equation presented) and (Equation presented) points, both of which have almost the same band energy. Thus Berkdemir's model should be used for (Equation presented) and our model for (Equation presented)
