′�?, by using a frequency of 295 cm−1, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−one phonon corresponds on the crystal IR absorption edge, as opposed to the residual absorption peak. Density useful concept computations display which the residual absorption with the https://baga4se7-crystal64528.blogdal.com/33075173/the-smart-trick-of-baga4se7-crystal-that-nobody-is-discussing
