In the framework of the Wall-Co research project, a 3-year PhD position is opened in CEA-SPEC.
Summary: Ferroelectrics are insulating by nature but the recent discovery of domain wall conduction has triggered a new era for these materials: domain walls exhibit very different electronic properties and can be controlled (written or erased) under application of low power electrical fields. They are naturally nano-sized and therefore highly scalable. The conceptual breach is based here on the domain wall itself becoming the active element of the device. Under certain conditions charged domain walls can be created with true metallic conduction, orders of magnitude higher than in bulk domains through quasi 2D electron gas at the domain wall. The conductivity may be chemically or electrically controlled. The aim of the project is to realize, study and control such charged domain walls in BaTiO3.
