THE BEST SIDE OF BAGA4SE7 CRYSTAL

′�?, having a frequency of 295 cm−1, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption in the 295 cm−one phonon corresponds for the crystal IR absorption edge, in lieu of the residual absorption peak. Density purposeful principle computations exhibit which the residual absorption on the BGSe crystal origina
