′�?, by using a frequency of 295 cm−one, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption in the 295 cm−1 phonon corresponds on the crystal IR absorption edge, instead of the residual absorption peak. Density functional idea computations demonstrate which the residual absorption of the BGSe https://baga4se7crystal57901.blogchaat.com/32833008/how-much-you-need-to-expect-you-ll-pay-for-a-good-baga4se7-crystal
