Witryna31 lip 2014 · For well-crystallized NiO thin films, the dielectric nonlinearity is observed after annealed at higher temperatures. The mechanisms leading to these dielectric responses are illuminated in detail. Finally, NiO thin film capacitors annealed at 300 °C present the highest tunability (68.1% @100 kHz) under a small applied field of 82 kV/cm. Witryna1 maj 2004 · The analysis of the absorption coefficient spectra of the thin films in the range of photon energies E=0.4–4 eV region reveals the contribution from different …
