THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NO ONE IS DISCUSSING

′�?, having a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption from the 295 cm−1 phonon corresponds to the crystal IR absorption edge, instead of the residual absorption peak. Density useful concept computations present that the residual absorption from the BGSe crystal originates
