′�?, using a frequency of 295 cm−one, is attributed on the stretching vibration of Ga–Se bonds. The two-phonon absorption of your 295 cm−one phonon corresponds towards the crystal IR absorption edge, as an alternative to the residual absorption peak. Density useful concept computations present that the residual absorption in the https://baga4se7-crystal30738.blogsidea.com/39007007/helping-the-others-realize-the-advantages-of-baga4se7-crystal
