′�?, having a frequency of 295 cm−one, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption in the 295 cm−1 phonon corresponds to the crystal IR absorption edge, rather than the residual absorption peak. Density functional idea computations exhibit the residual absorption from the BGSe crystal originates https://thomasz111pdo5.salesmanwiki.com/user
