THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NOBODY IS DISCUSSING

′�?, having a frequency of 295 cm−1, is attributed on the stretching vibration of Ga–Se bonds. The two-phonon absorption in the 295 cm−one phonon corresponds on the crystal IR absorption edge, as opposed to the residual absorption peak. Density purposeful theory computations exhibit the residual absorption from the BGSe crystal originates
