dc.description.abstract | Electroreduction experiments on metal oxides are well established for investigating the nature of
the material change in memresistive devices, whose basic working principle is an electrically-induced
reduction. While numerous research studies on this topic have been conducted, the influence of
extended defects such as dislocations has not been addressed in detail hitherto. Here, we show by
employing thermal microscopy to detect local Joule heating effects in the first stage of electroreduction
of SrTiO3 that the current is channelled along extended defects such as dislocations which were
introduced mechanically by scratching or sawing. After prolonged degradation, the matrix of the
crystal is also electroreduced and the influence of the initially present dislocations diminished. At this
stage, a hotspot at the anode develops due to stoichiometry polarisation leading not only to the gliding
of existing dislocations, but also to the evolution of new dislocations. Such a formation is caused by
electrical and thermal stress showing dislocations may play a significant role in resistive switching
effects. | pl_PL |
