BAGA4SE7 CRYSTAL CAN BE FUN FOR ANYONE

′�?, using a frequency of 295 cm−one, is attributed towards the stretching vibration of Ga–Se bonds. The two-phonon absorption on the 295 cm−one phonon corresponds to the crystal IR absorption edge, rather then the residual absorption peak. Density useful theory computations exhibit that the residual absorption on the BGSe crystal origina
