摘      要：The charged domain wall is an ultrathin(typically nanosized)interface between two domains;it carries bound charge owing to a change of normal component of spontaneous polarization on crossing the *** contrast to hetero-interfaces between different materials,charged domain walls(CDWs)can be created,displaced,erased,and recreated again in the bulk of a *** of the bound charge with free carriers is often necessary for stability of CDWs,which can result in giant two-dimensional conductivity along the *** in nominally insulating ferroelectrics,the concentration of free carriers at the walls can approach metallic ***,CDWs can be viewed as ultrathin reconfigurable strongly conductive sheets embedded into the bulk of an insulating *** feature is highly attractive for future *** last decade was marked by a surge of research interest in *** resulted in numerous breakthroughs in controllable and reproducible fabrication of CDWs in different materials,in investigation of CDW properties and charge compensation mechanisms,in discovery of light-induced effects,and,finally,in detection of giant two-dimensional *** present review is aiming at a concise presentation of the main physical ideas behind CDWs and a brief overview of the most important theoretical and experimental findings in the field.
