CONSIDERATIONS TO KNOW ABOUT BAGA4SE7 CRYSTAL

′�?, using a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The two-phonon absorption on the 295 cm−one phonon corresponds on the crystal IR absorption edge, instead of the residual absorption peak. Density useful concept computations clearly show which the residual absorption in the BGSe crystal origi
