HELPING THE OTHERS REALIZE THE ADVANTAGES OF BAGA4SE7 CRYSTAL

′�?, having a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The two-phonon absorption of the 295 cm−1 phonon corresponds to the crystal IR absorption edge, as an alternative to the residual absorption peak. Density functional principle computations present that the residual absorption in the BGSe crys
