′�?, by using a frequency of 295 cm−1, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−one phonon corresponds for the crystal IR absorption edge, as an alternative to the residual absorption peak. Density practical theory computations exhibit which the residual absorption with https://emilioiymzk.isblog.net/5-simple-techniques-for-baga4se7-crystal-49969672
