BAGA4SE7 CRYSTAL CAN BE FUN FOR ANYONE

′�?, that has a frequency of 295 cm−1, is attributed to the stretching vibration of Ga–Se bonds. The two-phonon absorption on the 295 cm−one phonon corresponds into the crystal IR absorption edge, as opposed to the residual absorption peak. Density useful theory computations clearly show the residual absorption in the BGSe crystal origina
