′�?, using a frequency of 295 cm−one, is attributed into the stretching vibration of Ga–Se bonds. The 2-phonon absorption in the 295 cm−one phonon corresponds to your crystal IR absorption edge, as an alternative to the residual absorption peak. Density practical idea computations display which the residual absorption on the https://johnnybehhh.theobloggers.com/38989260/not-known-details-about-baga4se7-crystal
