′�?, which has a frequency of 295 cm−one, is attributed into the stretching vibration of Ga–Se bonds. The 2-phonon absorption in the 295 cm−1 phonon corresponds on the crystal IR absorption edge, as opposed to the residual absorption peak. Density useful concept computations display that the residual absorption of the https://baga4se7crystal39517.glifeblog.com/31834840/top-guidelines-of-baga4se7-crystal
