′�?, with a frequency of 295 cm−1, is attributed towards the stretching vibration of Ga–Se bonds. The two-phonon absorption from the 295 cm−one phonon corresponds into the crystal IR absorption edge, rather then the residual absorption peak. Density purposeful theory computations exhibit the residual absorption in the BGSe crystal originates https://baga4se7crystal41341.bloggactivo.com/31821080/a-secret-weapon-for-baga4se7-crystal
