′�?, with a frequency of 295 cm−one, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−1 phonon corresponds to your crystal IR absorption edge, rather then the residual absorption peak. Density practical concept computations exhibit the residual absorption of the BGSe crystal originates https://samira221qdo6.magicianwiki.com/user
