′�?, which has a frequency of 295 cm−1, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−one phonon corresponds on the crystal IR absorption edge, as opposed to the residual absorption peak. Density functional theory computations present that the residual absorption in the https://ralstonw009mzl4.hazeronwiki.com/user
