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−1 phonon corresponds into the crystal IR absorption edge, as an alternative to the residual absorption peak. Density functional idea computations display the residual absorption in the BGSe crystal origi
