′�?, with a frequency of 295 cm−1, is attributed towards the stretching vibration of Ga–Se bonds. The two-phonon absorption of the 295 cm−1 phonon corresponds to your crystal IR absorption edge, as opposed to the residual absorption peak. Density purposeful principle computations clearly show which the residual absorption from the https://baga4se7crystal46780.blogdiloz.com/31782887/the-smart-trick-of-baga4se7-crystal-that-nobody-is-discussing
