′�?, that has a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The two-phonon absorption of the 295 cm−one phonon corresponds to the crystal IR absorption edge, as an alternative to the residual absorption peak. Density practical theory computations present which the residual absorption of https://baga4se7crystal46890.dailyblogzz.com/32989164/the-ultimate-guide-to-baga4se7-crystal
