There are phenomena which are not expected to be able to co-exist within the same system. One of the most notable examples is superconductivity and magnetism, which was overturned by the discovery of iron-based superconductors. Here, the authors report the co-existence of another pair of mutually antagonistic properties-polarity and two-dimensional conductivity-in ferroelectric thin films and analyse the mechanisms which sustain them.
