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

′�?, having a frequency of 295 cm−1, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption of the 295 cm−one phonon corresponds into the crystal IR absorption edge, instead of the residual absorption peak. Density functional theory computations clearly show which the residual absorption with the BGSe cryst
