44. Our calculations presented in this paper are all done at Tlat =0, when phonon absorption can be neglected. At finite lattice temperature, phonon absorption becomes finite. However, its behavior will not be significantly different from emission as it will also be dominated by zone center phonons and limited by the phonon density of states.
