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

′�?, with a frequency of 295 cm−one, is attributed to the stretching vibration of Ga–Se bonds. The two-phonon absorption in the 295 cm−one phonon corresponds to the crystal IR absorption edge, rather than the residual absorption peak. Density purposeful theory computations demonstrate the residual absorption of the BGSe crystal originates
