′�?, using a frequency of 295 cm−one, is attributed into the stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−one phonon corresponds for the crystal IR absorption edge, as an alternative to the residual absorption peak. Density practical idea computations demonstrate that the residual absorption of your https://baga4se7crystal20617.total-blog.com/everything-about-baga4se7-crystal-58034781
