BAGA4SE7 CRYSTAL FUNDAMENTALS EXPLAINED

′�?, by using a frequency of 295 cm−1, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−1 phonon corresponds on the crystal IR absorption edge, instead of the residual absorption peak. Density useful principle computations exhibit the residual absorption in the BGSe crystal originates with th
