′�?, that has a frequency of 295 cm−1, is attributed towards the stretching vibration of Ga–Se bonds. The two-phonon absorption from the 295 cm−one phonon corresponds into the crystal IR absorption edge, rather then the residual absorption peak. Density useful theory computations clearly show that the residual absorption from the https://gregoryntwyy.buyoutblog.com/32726837/the-smart-trick-of-baga4se7-crystal-that-nobody-is-discussing
