NOT KNOWN FACTUAL STATEMENTS ABOUT BAGA4SE7 CRYSTAL

′�?, that has a frequency of 295 cm−1, is attributed into the stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−1 phonon corresponds towards the crystal IR absorption edge, as an alternative to the residual absorption peak. Density practical idea computations demonstrate the residual absorption of your BGSe crysta
