5 EASY FACTS ABOUT BAGA4SE7 CRYSTAL DESCRIBED

′�?, having a frequency of 295 cm−one, is attributed into the stretching vibration of Ga–Se bonds. The two-phonon absorption on the 295 cm−one phonon corresponds into the crystal IR absorption edge, instead of the residual absorption peak. Density purposeful concept computations show the residual absorption on the BGSe crystal originates
