HOW MUCH YOU NEED TO EXPECT YOU'LL PAY FOR A GOOD BAGA4SE7 CRYSTAL

′�?, with a frequency of 295 cm−1, is attributed to the stretching vibration of Ga–Se bonds. The two-phonon absorption with the 295 cm−1 phonon corresponds to the crystal IR absorption edge, as opposed to the residual absorption peak. Density practical idea computations clearly show which the residual absorption in the BGSe crystal origin
