NEW STEP BY STEP MAP FOR BAGA4SE7 CRYSTAL

′�?, with a frequency of 295 cm−one, is attributed for the stretching vibration of Ga–Se bonds. The two-phonon absorption on the 295 cm−one phonon corresponds into the crystal IR absorption edge, in lieu of the residual absorption peak. Density practical theory computations demonstrate the residual absorption with the BGSe crystal origina
