NEW STEP BY STEP MAP FOR BAGA4SE7 CRYSTAL

′�?, that has a frequency of 295 cm−one, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−1 phonon corresponds for the crystal IR absorption edge, in lieu of the residual absorption peak. Density useful concept computations show which the residual absorption with the BGSe crystal originates
