′�?, using a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−1 phonon corresponds towards the crystal IR absorption edge, as an alternative to the residual absorption peak. Density functional theory computations display which the residual absorption of your https://finnlcpan.link4blogs.com/54271697/not-known-details-about-baga4se7-crystal
