THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NOBODY IS DISCUSSING

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