THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NOBODY IS DISCUSSING

′�?, which has a frequency of 295 cm−one, is attributed towards the stretching vibration of Ga–Se bonds. The two-phonon absorption in the 295 cm−1 phonon corresponds on the crystal IR absorption edge, rather than the residual absorption peak. Density functional idea computations exhibit the residual absorption of the BGSe crystal originat
