THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NOBODY IS DISCUSSING

′�?, which has a frequency of 295 cm−1, is attributed on the stretching vibration of Ga–Se bonds. The two-phonon absorption of the 295 cm−one phonon corresponds on the crystal IR absorption edge, in lieu of the residual absorption peak. Density practical theory computations exhibit which the residual absorption of your BGSe crystal origin
