′�?, which 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 for the crystal IR absorption edge, as opposed to the residual absorption peak. Density purposeful idea computations show which the residual absorption with the https://myleseviug.humor-blog.com/31824113/the-smart-trick-of-baga4se7-crystal-that-nobody-is-discussing
