′�?, by using a frequency of 295 cm−one, is attributed on the stretching vibration of Ga–Se bonds. The two-phonon absorption of the 295 cm−one phonon corresponds to your crystal IR absorption edge, in lieu of the residual absorption peak. Density practical idea computations present that the residual absorption of your https://baga4se7crystal15689.blogofoto.com/63927263/what-does-baga4se7-crystal-mean
