BAGA4SE7 CRYSTAL CAN BE FUN FOR ANYONE

′�?, with a frequency of 295 cm−one, is attributed to the stretching vibration of Ga–Se bonds. The two-phonon absorption with the 295 cm−one phonon corresponds into the crystal IR absorption edge, instead of the residual absorption peak. Density useful theory computations show that the residual absorption on the BGSe crystal originates wi
