′�?, using a frequency of 295 cm−one, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−1 phonon corresponds to the crystal IR absorption edge, rather than the residual absorption peak. Density useful idea computations exhibit the residual absorption of the BGSe crystal originates https://garrettafggc.prublogger.com/32000231/everything-about-baga4se7-crystal
