Notes:
The bulk amorphous-like (a-) semiconductor, a-ZnIn2Te4, is prepared by the melt-quench technique. The pseudodielectric-function spectra, 〈ε(E)〉=〈ε1(E)〉+i〈ε2(E)〉, of a-ZnIn2Te4 are measured by spectroscopic ellipsometry in the 1.2–5.3 eV photon-energy range at room temperature. The measured 〈ε(E)〉 spectra strongly resemble those of amorphous tetrahedrally bonded semiconductors. These spectra are analyzed using a simplified model of the interband optical transitions. Dielectric-related optical constants, such as the complex refractive index, absorption coefficient, and normal-incidence reflectivity, of a-ZnIn2Te4 are also been presented. © 1999 American Institute of Physics.
