BAGA4SE7 CRYSTAL CAN BE FUN FOR ANYONE

′�?, by using a frequency of 295 cm−one, is attributed to the stretching vibration of Ga–Se bonds. The two-phonon absorption in the 295 cm−one phonon corresponds to the crystal IR absorption edge, in lieu of the residual absorption peak. Density functional concept computations present the residual absorption with the BGSe crystal originat
