′�?, with a frequency of 295 cm−1, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−1 phonon corresponds into the crystal IR absorption edge, rather than the residual absorption peak. Density purposeful principle computations display the residual absorption of the BGSe crystal originates https://sergioloqro.eedblog.com/32911017/5-easy-facts-about-baga4se7-crystal-described
