BAGA4SE7 CRYSTAL CAN BE FUN FOR ANYONE

′�?, having a frequency of 295 cm−1, is attributed to the stretching vibration of Ga–Se bonds. The two-phonon absorption from the 295 cm−1 phonon corresponds towards the crystal IR absorption edge, as opposed to the residual absorption peak. Density purposeful principle computations display the residual absorption from the BGSe crystal or
