Manipulating the Hydrogen-Associated Insulator-Metal Transition Through Artificial Microstructure Engineering.

ABSTRACT: Hydrogen-associated filling-controlled Mottronics within electron-correlated system provides a groundbreaking paradigm to explore exotic physical functionality and phenomena. Dynamically controlling hydrogen-related phase transitions through external fields offers a promising route for designing protonic devices in multidisciplinary fields but faces high-speed bottlenecks owing to slow bulk diffusion of hydrogens. Here, a promising pathway is presented to kinetically expedite the electronic state evolution in VO₂ system by taking advantage of artificial microstructure design. Typically, inclined domain boundary configuration and c_R-faceted preferential orientation, simultaneously realized in VO₂/Al₂O₃ (1 1¯$\bar 1$ 02) heterostructure,
