      abstract     = {Laterally structured materials can exhibit properties
                      uniquely suited for applications in electronics,
                      magnetoelectric memory, photonics, and nanoionics. Here, a
                      patterning approach is presented that combines the precise
                      geometric control enabled by lithography with topochemical
                      anionic manipulation of complex oxide films. Utilizing
                      oxidation and fluorination reactions, striped patterns of
                      SrFeO2.5/SrFeO3,SrFeO2.5/SrFeO2F, and SrFeO3/SrFeO2F have
                      been prepared with lateral periodicities of 200, 20, and 4
                      μm. Coexistence of the distinct chemical phases is
                      confirmed through x-ray diffraction, optical and
                      photoemission microscopies, and optical spectroscopy. The
                      lateral heterostructures exhibit highly anisotropic
                      electronic transport and also enable transience and
                      regeneration of patterns through reversible redox reactions.
                      This approach can be broadly applied to a variety of
                      metal-oxide systems, enabling chemically reconfigurable
                      lateral heterostructures tailored for specific electronic,
                      optical, ionic, thermal, or magnetic functionalities.},
