′�?, having a frequency of 295 cm−one, is attributed to the stretching vibration of Ga–Se bonds. The two-phonon absorption from the 295 cm−1 phonon corresponds on the crystal IR absorption edge, as an alternative to the residual absorption peak. Density practical idea computations present which the residual absorption of your https://baga4se7-crystal89124.mpeblog.com/57580465/5-simple-techniques-for-baga4se7-crystal
