′�?, by using a frequency of 295 cm−one, is attributed into the stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−1 phonon corresponds into the crystal IR absorption edge, as an alternative to the residual absorption peak. Density practical idea computations display which the residual absorption on https://rylanxcehf.tribunablog.com/baga4se7-crystal-an-overview-47175414
