摘要	Charged domain walls in ferroelectric materials exhibit nontrivial electronic and transport properties, which have promising application in many electronic devices, such as high-density nonvolatile memories. Taking advantage of oxygen vacancy engineering, charged domain walls are introduced into the PbTiO3/LaCoO2.5 superlattice system, and the quasi-two-dimensional electron gas is formed near the domain walls, featuring an intrinsic n-type conductive characteristic. The charged domain walls can be erased by eliminating oxygen vacancies in the LaCoO2.5, resulting in an insulating state. The proposed scheme of writing and erasing of charged domain walls may facilitate the development of domain wall based devices.
