THE SMART TRICK OF BAGA4SE7 CRYSTAL THAT NOBODY IS DISCUSSING

′�?, having a frequency of 295 cm−one, is attributed towards the stretching vibration of Ga–Se bonds. The two-phonon absorption of the 295 cm−one phonon corresponds into the crystal IR absorption edge, rather then the residual absorption peak. Density functional concept computations clearly show which the residual absorption in the BGSe c
