NOT KNOWN FACTS ABOUT BAGA4SE7 CRYSTAL

′�?, which has a frequency of 295 cm−1, is attributed into the stretching vibration of Ga–Se bonds. The 2-phonon absorption from the 295 cm−one phonon corresponds on the crystal IR absorption edge, in lieu of the residual absorption peak. Density useful principle computations display which the residual absorption with the BGSe crystal ori
