GETTING MY BAGA4SE7 CRYSTAL TO WORK

′�?, that has a frequency of 295 cm−one, is attributed for the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−1 phonon corresponds to the crystal IR absorption edge, rather then the residual absorption peak. Density practical principle computations clearly show that the residual absorption in the BGSe crystal
