CONSIDERATIONS TO KNOW ABOUT BAGA4SE7 CRYSTAL

′�?, by using a frequency of 295 cm−one, is attributed on the stretching vibration of Ga–Se bonds. The 2-phonon absorption from the 295 cm−1 phonon corresponds towards the crystal IR absorption edge, rather than the residual absorption peak. Density practical concept computations show that the residual absorption from the BGSe crystal ori
