NOT KNOWN FACTUAL STATEMENTS ABOUT BAGA4SE7 CRYSTAL

′�?, with a frequency of 295 cm−one, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption from the 295 cm−one phonon corresponds towards the crystal IR absorption edge, rather then the residual absorption peak. Density practical idea computations clearly show which the residual absorption in the BGSe crys
