The back cover shows an optical microscopy image (100×) of microdomains of nanostructured p‐type CuFeO 2 and n‐type Fe 2 O 3 that emerge from a single facile solution‐processed thin film. This film, as discussed by K. Sivula and co‐workers on page 9308, when employed as a photoelectrode, demonstrates switchable operation controlled by chemical, optical, or electronic inputs with a uniquely high photocurrent response suitable for robust practical application as an oxygen photo‐regulator, or for ternary logic signal transduction.
