′�?, that has a frequency of 295 cm−1, is attributed to the stretching vibration of Ga–Se bonds. The two-phonon absorption with the 295 cm−1 phonon corresponds towards the crystal IR absorption edge, instead of the residual absorption peak. Density purposeful principle computations display which the residual absorption of your BGSe https://warrend937yab4.wikifiltraciones.com/user
