THE BEST SIDE OF BAGA4SE7 CRYSTAL

′�?, which has a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−1 phonon corresponds to the crystal IR absorption edge, instead of the residual absorption peak. Density functional idea computations display which the residual absorption in the BGSe crystal origina
