′�?, which has a frequency of 295 cm−one, is attributed into the stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−one phonon corresponds for the crystal IR absorption edge, as opposed to the residual absorption peak. Density functional theory computations show which the residual absorption of your https://garrettahfax.widblog.com/87743243/not-known-details-about-baga4se7-crystal
