′�?, which has a frequency of 295 cm−1, is attributed into the stretching vibration of Ga–Se bonds. The two-phonon absorption of your 295 cm−1 phonon corresponds towards the crystal IR absorption edge, as opposed to the residual absorption peak. Density functional principle computations present which the residual absorption on the https://baga4se7crystal18428.bloggazzo.com/31967871/the-smart-trick-of-baga4se7-crystal-that-no-one-is-discussing
