RUMORED BUZZ ON BAGA4SE7 CRYSTAL

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