Robust Hierarchically Structured Biphasic Ambipolar Oxide Photoelectrodes for Light-Driven Chemical Regulation and Switchable Logic Applications.
Tunable ambipolar photoelectrochemical behavior emerges from microdomains of nanostructured p-type CuFeO2and n-type Fe2O3that arise from a single facile solution-processed thin film. The switchable operation of this system is controlled by chemical, optical, or electronic inputs with a uniquely high photocurrent response (on the order of 1 mA cm-2), suitable for robust practical application as an oxygen photoregulator.
