′�?, by using a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption in the 295 cm−one phonon corresponds to your crystal IR absorption edge, in lieu of the residual absorption peak. Density practical idea computations exhibit that the residual absorption of your https://kameronzcbvq.blogkoo.com/top-guidelines-of-baga4se7-crystal-52236304
