′�?, that has a frequency of 295 cm−one, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption on the 295 cm−1 phonon corresponds into the crystal IR absorption edge, in lieu of the residual absorption peak. Density practical concept computations demonstrate which the residual absorption on the https://baga4se7-crystal52852.bloguetechno.com/everything-about-baga4se7-crystal-67808672
