′�?, having a frequency of 295 cm−one, is attributed into the stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−one phonon corresponds for the crystal IR absorption edge, instead of the residual absorption peak. Density purposeful principle computations display that the residual absorption of your BGSe crystal https://emilioduhsd.blogthisbiz.com/39384964/the-smart-trick-of-baga4se7-crystal-that-nobody-is-discussing
