WHAT DOES BAGA4SE7 CRYSTAL MEAN?

′�?, that has a frequency of 295 cm−one, is attributed for the stretching vibration of Ga–Se bonds. The two-phonon absorption from the 295 cm−one phonon corresponds into the crystal IR absorption edge, as opposed to the residual absorption peak. Density purposeful principle computations present which the residual absorption of the BGSe cr
