THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NO ONE IS DISCUSSING

′�?, by using a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The two-phonon absorption on the 295 cm−one phonon corresponds to the crystal IR absorption edge, rather than the residual absorption peak. Density functional principle computations show that the residual absorption of the BGSe crystal orig
