THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NOBODY IS DISCUSSING

′�?, that has a frequency of 295 cm−one, is attributed into the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−1 phonon corresponds into the crystal IR absorption edge, instead of the residual absorption peak. Density practical theory computations display that the residual absorption of the BGSe crystal origin
