′�?, having a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The two-phonon absorption of your 295 cm−1 phonon corresponds towards the crystal IR absorption edge, instead of the residual absorption peak. Density practical principle computations show the residual absorption with the BGSe crystal originates https://busterj947mhz1.wikipublicist.com/user
