BAGA4SE7 CRYSTAL CAN BE FUN FOR ANYONE

′�?, using a frequency of 295 cm−one, is attributed on the stretching vibration of Ga–Se bonds. The two-phonon absorption from the 295 cm−one phonon corresponds on the crystal IR absorption edge, as an alternative to the residual absorption peak. Density purposeful theory computations display the residual absorption of the BGSe crystal or
