Electrical and optical properties of TlIn1−x Ce x Se2 (0 ≤ x ≤ 0.04) single crystals

Electrical and optical properties of TlIn1−x Ce x Se2 (0 ≤ x ≤ 0.04) single crystals

We have measured the temperature-dependent electrical conductivity (77-800 K), photoconductivity spectra, and optical reflectivity spectra (1-6 eV) of TlIn1-x Ce x Se2 single crystals. The results were used to evaluate the activation energy of impurities in the crystals and their band gap, refractiv...

Zusammenfassung:We have measured the temperature-dependent electrical conductivity (77-800 K), photoconductivity spectra, and optical reflectivity spectra (1-6 eV) of TlIn1-x Ce x Se2 single crystals. The results were used to evaluate the activation energy of impurities in the crystals and their band gap, refractive index, and dielectric permittivity.
