THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NO ONE IS DISCUSSING

′�?, with a frequency of 295 cm−one, is attributed into the stretching vibration of Ga–Se bonds. The two-phonon absorption in the 295 cm−1 phonon corresponds to the crystal IR absorption edge, rather than the residual absorption peak. Density purposeful concept computations clearly show that the residual absorption from the BGSe crystal o
