NEW STEP BY STEP MAP FOR BAGA4SE7 CRYSTAL

′�?, by using a frequency of 295 cm−one, is attributed into the stretching vibration of Ga–Se bonds. The two-phonon absorption with the 295 cm−one phonon corresponds for the crystal IR absorption edge, rather then the residual absorption peak. Density functional principle computations display which the residual absorption of the BGSe crys
