BAGA4SE7 CRYSTAL CAN BE FUN FOR ANYONE

′�?, having a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−1 phonon corresponds to your crystal IR absorption edge, rather then the residual absorption peak. Density purposeful principle computations demonstrate that the residual absorption of the BGSe crystal or
