THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NO ONE IS DISCUSSING

′�?, which has a frequency of 295 cm−one, is attributed into the stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−one phonon corresponds towards the crystal IR absorption edge, instead of the residual absorption peak. Density purposeful principle computations demonstrate that the residual absorption from the BG
