′�?, with a frequency of 295 cm−one, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption of the 295 cm−one phonon corresponds to the crystal IR absorption edge, as an alternative to the residual absorption peak. Density practical theory computations exhibit which the residual absorption of the https://baga4se7crystal46801.blogsumer.com/31949682/the-smart-trick-of-baga4se7-crystal-that-no-one-is-discussing
