′�?, 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 to your crystal IR absorption edge, in lieu of the residual absorption peak. Density functional principle computations show which the residual absorption of your https://baga4se7-crystal91346.blog-eye.com/32937698/not-known-factual-statements-about-baga4se7-crystal
