′�?, using a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The two-phonon absorption of the 295 cm−1 phonon corresponds on the crystal IR absorption edge, rather then the residual absorption peak. Density useful concept computations demonstrate the residual absorption of the BGSe crystal originates https://anneliu581efd5.qodsblog.com/profile
