′�?, with a frequency of 295 cm−one, is attributed into the stretching vibration of Ga–Se bonds. The 2-phonon absorption of the 295 cm−1 phonon corresponds to the crystal IR absorption edge, instead of the residual absorption peak. Density functional principle computations show the residual absorption in the BGSe crystal originates https://heinzc222rfr6.ambien-blog.com/profile
