Chemical expansion of CeO_2−δ and Ce_0.8Zr_0.2O_2−δ thin films determined by laser Doppler vibrometry at high temperatures and different oxygen partial pressures

The chemical expansion of ceria (CeO_2−δ) and ceria-zirconia (Ce_0.8Zr_0.2O_2−δ, CZO80) thin films is investigated by high-temperature laser Doppler vibrometry (LDV) at temperatures from 600 to 950 °C. The films are ...

Comparison of the electrical conductivity of bulk and film Ce_1–xZr_xO_2–δ in oxygen-depleted atmospheres at high temperatures

Featuring high levels of achievable oxygen non-stoichiometry δ, Ce_1−xZr_xO_2−δ solid solutions (CZO) are crucial for application as oxygen storage materials in, for example, automotive three-way catalytic converter...
