A SECRET WEAPON FOR BAGA4SE7 CRYSTAL

′�?, by using a frequency of 295 cm−one, is attributed into the stretching vibration of Ga–Se bonds. The 2-phonon absorption in the 295 cm−1 phonon corresponds to the crystal IR absorption edge, as opposed to the residual absorption peak. Density practical concept computations present the residual absorption in the BGSe crystal originates
