Lattice-regulated non-equilibrium pathways in functional oxides
Abstract
Energy-transduction systems, such as electrolysers or photocatalysts, operate under driven non-equilibrium conditions. Although the dynamical evolution governs the functional output, programming such pathways remains a challenge because the relationship between structure and dynamics is hard to ascertain and control on demand. Herein we use strain profiles to instil controlled static lattice perturbations and probe their impact on the non-equilibrium energy landscape. Using BiVO4 as a model system, we find that strain modifies the non-equilibrium pathways of reactive holes and regulates their population. Kinetic analyses show that a 1% strain-driven compression of the unit cell enhances the yield of photogenerated holes by ~30 % while cell dilation reduces their availability. Our results evidence structure-dynamics relationships and expose a direct coupling between static lattice distortions and the driven non-equilibrium response. More broadly, they establish strain-control as a route to program functionality in energy solids via regulation of dynamical pathways.
