CONSIDERATIONS TO KNOW ABOUT BAGA4SE7 CRYSTAL

′�?, by using a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−one phonon corresponds to the crystal IR absorption edge, instead of the residual absorption peak. Density purposeful idea computations show that the residual absorption of your BGSe crystal originates
