′�?, by using a frequency of 295 cm−one, is attributed towards the stretching vibration of Ga–Se bonds. The two-phonon absorption on the 295 cm−one phonon corresponds to the crystal IR absorption edge, in lieu of the residual absorption peak. Density functional concept computations present that the residual absorption of your https://baga2gese6-crystal35689.blazingblog.com/32702423/what-does-baga4se7-crystal-mean
