Reflectivity spectrum and electrical properties of TlIn0.98Ce0.02Se2 single crystals

The room-temperature reflectivity spectrum of TlIn0.98Ce0.02Se2 crystals is measured at photon energies from 1 to 6 eV, and their conductivity, Hall coefficient, and thermoelectric power are determined in the temperature range 80-460 K. The results are used to evaluate the ionization energy of impur...

Beschreibung
Zusammenfassung:The room-temperature reflectivity spectrum of TlIn0.98Ce0.02Se2 crystals is measured at photon energies from 1 to 6 eV, and their conductivity, Hall coefficient, and thermoelectric power are determined in the temperature range 80-460 K. The results are used to evaluate the ionization energy of impurities (DeltaE a = 0.09 eV), the band gap of the crystals (E g = 1.30 eV), and their refractive index (n = 2.5).
