???, by using a frequency of 295 cm?one, is attributed into the stretching vibration of Ga–Se bonds. The two-phonon absorption of the 295 cm?one phonon corresponds to the crystal IR absorption edge, as an alternative to the residual absorption peak. Density purposeful idea computations show that the residual absorption on the BGSe crystal origina… Read More

The diffraction spectrum from the polycrystalline components is properly similar to the common JC-PDF card in accordance with the reflective peak. The effects reveal which the polycrystalline resources are significant-good quality AgGaGeS4 polycrystals with one stage. Single crystal was synthesized effectively by using the AgGaGeS4 polycrystals. So… Read More
