In oxides which exhibit electronic, protonic and oxide ion conductivity, water incorporation can lead to a kinetic build-up of redox gradients. We use Fe-doped SrTiO₃, the defect chemistry of which is very well understood to follow the thus generated electromotive force (EMF) as a function of time. In contrast to previous works we include trapping effects in the kinetic description. The agreement between the kinetic modelling and the experimental results is remarkable, given the complexity of the process.

将水掺入具有三个移动载体的材料中：掺铁的SrTiO _3中电动势的两倍松弛和空穴陷阱的重要性

在表现出电子，质子和氧化物离子导电性的氧化物中，水的掺入会导致氧化还原梯度的动力学累积。我们使用掺铁的SrTiO ₃，其缺陷化学性质非常了解其随时间而变化，从而遵循由此产生的电动势（EMF）。与以前的工作相反，我们在动力学描述中包括了陷阱效应。考虑到过程的复杂性，动力学建模和实验结果之间的一致性是显着的。
