THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NOBODY IS DISCUSSING

′�?, which has a frequency of 295 cm−one, is attributed for the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−one phonon corresponds towards the crystal IR absorption edge, as opposed to the residual absorption peak. Density functional theory computations show that the residual absorption on the BGSe crystal
