We have used energy-filtered photoemission electron microscopy (PEEM) at the photoemission threshold to carry out a microscopic scale characterization of the surface charge and domain structure of the (001) surface in BaTiO<sub>3</sub>. Signatures of ferroelectric and ferroelastic domains, and tweed, dominate the surface structure of BaTiO<sub>3</sub> at room temperature. The surface ferroic signatures are maintained on heating to temperature (~550 K), well above the transition temperature (393 ...[more]
