Figure 9

Optical gaps of a-\(\hbox {Si}_{1-x}\,\hbox {Ge}_{{x}}\) samples and the real and imaginary parts of the complex refractive indices at the wavelength of 633 nm (photon energy of 1.96 eV) modeled by CL (left-hand side) and TL (right-hand side) oscillators (graphs in the dotted frame). The other graphs show the x dependence of the fitted parameters utilizing the CL dispersion of Eq. (3), with the Broadening and Amplitude denoted by \(\Gamma \) and A, respectively.
