THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NO ONE IS DISCUSSING

′�?, with a frequency of 295 cm−one, is attributed into the stretching vibration of Ga–Se bonds. The 2-phonon absorption from the 295 cm−1 phonon corresponds into the crystal IR absorption edge, instead of the residual absorption peak. Density practical concept computations present which the residual absorption of the BGSe crystal origina
