′�?, using a frequency of 295 cm−one, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−1 phonon corresponds for the crystal IR absorption edge, in lieu of the residual absorption peak. Density useful idea computations show which the residual absorption of your BGSe https://baga4se7-crystal95184.creacionblog.com/32567410/the-smart-trick-of-baga4se7-crystal-that-nobody-is-discussing
