THE BEST SIDE OF BAGA4SE7 CRYSTAL

′�?, that has a frequency of 295 cm−one, is attributed into the stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−1 phonon corresponds towards the crystal IR absorption edge, in lieu of the residual absorption peak. Density useful principle computations clearly show that the residual absorption on the BGSe cryst
