′�?, by using a frequency of 295 cm−one, is attributed on the stretching vibration of Ga–Se bonds. The two-phonon absorption from the 295 cm−one phonon corresponds to your crystal IR absorption edge, in lieu of the residual absorption peak. Density practical idea computations demonstrate that the residual absorption in the https://baga4se7crystal19528.blogs100.com/33208960/the-smart-trick-of-baga4se7-crystal-that-nobody-is-discussing
