Exploring point defects and trap states in undoped SrTiO3 single crystals

Matthaeus Siebenhofer et al.

Summary: The defect chemistry and electronic trapping energies in undoped single crystalline SrTiO3 were investigated using electrochemical impedance spectroscopy and positron annihilation lifetime spectroscopy. The results showed that the chemical capacitance is a valuable tool for establishing a defect model based on electrochemical measurements and analyzing defect concentrations. The chemical capacitance analysis and positron annihilation lifetime spectroscopy are consistent in quantifying the defect concentrations in SrTiO3.

Correlating Surface Crystal Orientation and Gas Kinetics in Perovskite Oxide Electrodes

Ran Gao et al.

Summary: The efficiency of solid-oxide fuel cells and electrolyzers is determined by solid-gas interactions at electrode surfaces. The study on La0.8Sr0.2Co0.2Fe0.8O3 reveals a strong correlation between surface-gas kinetics and crystal orientation of perovskite electrodes, with (111)-oriented surfaces showing higher activity. Electrochemical impedance spectroscopy and electrical conductivity relaxation measurements indicate a surface-orientation dependency of gas-exchange kinetics, with all surfaces having the same reaction mechanisms and rate-limiting steps.

Oxygen transport in single-crystal LaAlO3 substrates

Christian Schwab et al.

Summary: The rates of oxygen incorporation and diffusion in cubic, nominally undoped LaAlO3 were investigated through isotope exchange experiments, yielding diffusion coefficient, exchange coefficient, and space-charge potential. The relatively high activation enthalpy for oxygen diffusion was attributed to vacancies interactions, while the surprisingly low activation enthalpy for oxygen surface exchange was noted despite the material's large band gap.
