′�?, with a frequency of 295 cm−one, is attributed into the stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−one phonon corresponds on the crystal IR absorption edge, as an alternative to the residual absorption peak. Density practical principle computations demonstrate which the residual absorption with the https://paxtoncsfrd.bloginder.com/33451345/5-simple-techniques-for-baga4se7-crystal
