RUMORED BUZZ ON BAGA4SE7 CRYSTAL

′�?, with a frequency of 295 cm−one, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption of the 295 cm−1 phonon corresponds to the crystal IR absorption edge, rather then the residual absorption peak. Density purposeful theory computations display the residual absorption of the BGSe crystal originates wi
