′�?, which has a frequency of 295 cm−1, is attributed for the stretching vibration of Ga–Se bonds. The two-phonon absorption in the 295 cm−one phonon corresponds to your crystal IR absorption edge, in lieu of the residual absorption peak. Density practical theory computations exhibit the residual absorption of your BGSe https://baga4se7crystal05837.blogdiloz.com/31617740/a-secret-weapon-for-baga4se7-crystal
