Best-match complex refractive indexes (, ) by using POC model for (a) GeTe, (b) , (c) , (d) , and (e) . Lines and lines with symbols denote refractive indices and extinction coefficients , respectively.
Second derivative spectra of the dielectric functions, , for (a) GeTe, (b) , (c) , (d) , and (e) . For simplicity, we denoted the CP energies as , in the order of increasing energy.
The optical transition and the CP energies of amorphous and crystalline (GeTe, ) pseudo-binary thin films, respectively. The uncertainty was about with 95% reliabilities.
