′�?, with a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The two-phonon absorption in the 295 cm−one phonon corresponds on the crystal IR absorption edge, instead of the residual absorption peak. Density useful principle computations show which the residual absorption from the BGSe crystal https://emperorq012yrj5.blog-a-story.com/profile
