NEW STEP BY STEP MAP FOR BAGA4SE7 CRYSTAL

′�?, having a frequency of 295 cm−1, is attributed into the stretching vibration of Ga–Se bonds. The two-phonon absorption of the 295 cm−one phonon corresponds for the crystal IR absorption edge, as opposed to the residual absorption peak. Density useful principle computations exhibit the residual absorption with the BGSe crystal originat
