BAGA4SE7 CRYSTAL CAN BE FUN FOR ANYONE

′�?, using a frequency of 295 cm−1, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption in the 295 cm−one phonon corresponds towards the crystal IR absorption edge, in lieu of the residual absorption peak. Density useful theory computations demonstrate which the residual absorption of the BGSe crystal origina
