CONSIDERATIONS TO KNOW ABOUT BAGA4SE7 CRYSTAL

′�?, that has a frequency of 295 cm−1, is attributed on the stretching vibration of Ga–Se bonds. The two-phonon absorption with the 295 cm−one phonon corresponds towards the crystal IR absorption edge, rather than the residual absorption peak. Density useful concept computations show which the residual absorption of the BGSe crystal origi
