A SECRET WEAPON FOR BAGA4SE7 CRYSTAL

′�?, which has a frequency of 295 cm−1, is attributed for the stretching vibration of Ga–Se bonds. The two-phonon absorption on the 295 cm−1 phonon corresponds for the crystal IR absorption edge, in lieu of the residual absorption peak. Density useful principle computations exhibit the residual absorption in the BGSe crystal originates fr
