THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NOBODY IS DISCUSSING

′�?, having a frequency of 295 cm−one, is attributed on the stretching vibration of Ga–Se bonds. The two-phonon absorption with the 295 cm−1 phonon corresponds for the crystal IR absorption edge, in lieu of the residual absorption peak. Density functional idea computations show the residual absorption in the BGSe crystal originates throug
