THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NOBODY IS DISCUSSING

′�?, having a frequency of 295 cm−1, is attributed on the stretching vibration of Ga–Se bonds. The 2-phonon absorption of the 295 cm−1 phonon corresponds to your crystal IR absorption edge, in lieu of the residual absorption peak. Density functional idea computations show the residual absorption from the BGSe crystal originates from the O
