′�?, by using a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The two-phonon absorption from the 295 cm−one phonon corresponds for the crystal IR absorption edge, as opposed to the residual absorption peak. Density practical concept computations display which the residual absorption with the https://baga4se7-crystal64074.ezblogz.com/64294167/a-secret-weapon-for-baga4se7-crystal
