THE BEST SIDE OF BAGA4SE7 CRYSTAL

′�?, having a frequency of 295 cm−one, is attributed for the stretching vibration of Ga–Se bonds. The 2-phonon absorption in the 295 cm−one phonon corresponds on the crystal IR absorption edge, instead of the residual absorption peak. Density useful principle computations show the residual absorption on the BGSe crystal originates from yo
