′�?, which has a frequency of 295 cm−1, is attributed into the stretching vibration of Ga–Se bonds. The 2-phonon absorption from the 295 cm−one phonon corresponds on the crystal IR absorption edge, instead of the residual absorption peak. Density purposeful theory computations demonstrate which the residual absorption of your BGSe https://felixizmuh.canariblogs.com/baga4se7-crystal-can-be-fun-for-anyone-47784571
