RUMORED BUZZ ON BAGA4SE7 CRYSTAL

′�?, by using a frequency of 295 cm−1, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption in the 295 cm−1 phonon corresponds into the crystal IR absorption edge, in lieu of the residual absorption peak. Density functional concept computations exhibit which the residual absorption in the BGSe crystal originat
