5 SIMPLE TECHNIQUES FOR BAGA4SE7 CRYSTAL

′�?, that has a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption from the 295 cm−1 phonon corresponds towards the crystal IR absorption edge, as opposed to the residual absorption peak. Density functional idea computations exhibit that the residual absorption of the BGSe crystal o
