A SECRET WEAPON 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 from the 295 cm−one phonon corresponds on the crystal IR absorption edge, instead of the residual absorption peak. Density purposeful idea computations display which the residual absorption with the BGSe crystal origi
