A SECRET WEAPON FOR BAGA4SE7 CRYSTAL

′�?, that has a frequency of 295 cm−one, is attributed into the stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−1 phonon corresponds for the crystal IR absorption edge, in lieu of the residual absorption peak. Density practical idea computations display which the residual absorption of your BGSe crystal origin
