Temperature-dependent polarization in a non-polar crystal

Temperature-dependent polarization in a non-polar crystal

A crystal’s surface has been found to behave as a distinct material that has temperature-dependent electrical polarization — despite the rest of the crystal being non-polar. Pyroelectricity in the surface layers of strontium titanate.
