“…Following the analogy with notations used in Ref. 42 for reflectivity spectra of semiconductors with zinc blende structure, the E 0 , E 1 , and E 2 peaks of In 2 O 3 -I and -II originate from optical transitions from VB maximum to CB minimum occurring at Γ-point for the E 0 peak, H and P points for the E 1 peak, and the N point for the E 2 peak. d 1 and d 2 peaks are, probably, originated from optical transitions from the In 4d states.…”

Structural phase stability, electronic structure, optical properties, and high-pressure behavior of polytypes of In 2 O 3 in three space group symmetry I2 1 3, Ia3 and R3 are studied by first-principles density functional calculations. From structural optimization studies lattice and positional parameters have been calculated, which are found to be in good agreement with the corresponding experimental data. In 2 O 3 of space group symmetry I2 1 3 and Ia3 are shown to undergo a pressureinduced phase transition to IO3 at pressures around 3.83 GPa. From analysis of band structure it is found that In 2 O 3 of space group symmetry I2 1 3 is indirect band gap semiconductors, while the other phase of space group Ia3 is direct band gap. The calculated carrier effective masses for all these three phases are compared with available experimental and theoretical values. From chargedensity and electron localization function analysis it is found that these phases have dominant ionic bonding. The magnitude of the absorption and reflection coefficients of In 2 O 3 with space group Ia3 and R3 are small in the energy range 0-5 eV, so that these materials can re regarded and classified as transparent.

“…The location and magnitude of the experimentally measured E 1 peak in the reflectivity spectra of ZnSe-z and ZnTe-z have been assigned 11,14 to fundamental absorption and Λ 3 − Λ 1 transitions at the [0.17, 0.17, 0.17] point of the Brillouin zone. These assignments agree well with theoretical calculations.…”

Electronic band structure and optical properties of zinc monochalcogenides with zinc-blende-and wurtzite-type structures were studied using the ab initio density functional method within the LDA, GGA, and LDA+U approaches. Calculations of the optical spectra have been performed for the energy range 0-20 eV, with and without including spin-orbit coupling. Reflectivity, absorption and extinction coefficients, and refractive index have been computed from the imaginary part of the dielectric function using the Kramers-Kronig transformations. A rigid shift of the calculated optical spectra is found to provide a good first approximation to reproduce experimental observations for almost all the zinc monochalcogenide phases considered. By inspection of the calculated and experimentally determined band-gap values for the zinc monochalcogenide series, the band gap of ZnO with zinc-blende structure has been estimated.

The dielectric properties of metallic Ti and thin films of TiO2 and TiN in the energy range from 1.5 to 60 eV have been determined by quantitative analysis of the respective electron energy loss spectra in the reflection mode (REELS). The energy loss function (ELF) of every material, that is proportional to Im {1/ε}, is obtained by trial and error until a good quantitative agreement between the simulated and experimental inelastic electron scattering cross‐sections at three different primary electron energies (i.e. 0.5, 1 and 1.5 keV) is achieved. Kramers‐Kronig transformation is then used to obtain real and imaginary parts of the dielectric function ε(ω). In addition, spectroscopic ellipsometry was used to improve the ELF in the 1.5 to 4.5 eV energy range where it is strongly affected by the experimental energy resolution and the presence of the elastic peak. The characteristic differences among the spectra of the particular compounds are discussed in terms of different electronic properties.
