ABO₃ perovskite-type oxides constitute some of the most fascinating materials in the solid state sciences, displaying a wide range of useful, interesting phenomena. Electrical conduction and ion diffusion — the transport of charge and mass — are two key phenomena, as they can be utilised directly or they often need to be tuned for the utilisation of other phenomena. This review focuses on how dislocations (one-dimensional lattice defects) affect charge and mass transport in ABO₃ perovskites. The main system of interest is SrTiO₃ because of the wealth of available studies, but other perovskites (e.g.LaMnO₃, BaSnO₃) are considered where appropriate. After a brief discussion of relevant basic aspects, literature is reviewed on the structure, composition and charge of dislocations in ABO₃ perovskite-type oxides, and on how such dislocations affect the transport of charge and mass. The role of dislocations in resistive switching is briefly discussed. Attention is drawn to a variety of open questions and critical issues.

固态科学中，AB O ₃钙钛矿型氧化物构成一些最引人入胜的材料，显示出各种有用的有趣现象。导电和离子扩散-电荷和质量的传输-是两个关键现象，因为它们可以直接使用，或者经常需要对其进行调整以利用其他现象。这篇综述的重点是位错（一维晶格缺陷）如何影响AB O ₃钙钛矿中的电荷和质量传输。由于有大量可用的研究，因此关注的主要系统是SrTiO ₃，但其他钙钛矿（例如LaMnO ₃，BaSnO ₃）在适当的情况下考虑。在简要讨论了相关的基本方面之后，回顾了有关AB O ₃钙钛矿型氧化物中位错的结构，组成和电荷以及此类位错如何影响电荷和质量迁移的文献。简要讨论了位错在电阻切换中的作用。请注意各种公开问题和关键问题。
