Mechanical Bending Strain-Actuated Modulation of Metal–Insulator Transition Temperature in Flexible Epitaxial V2O3 Films

“…The design and fabrication of flexible oxide films have recently attracted considerable interests. − Among various integration strategies utilized, the direct deposition of oxide films on a flexible inert mica substrate has caught much attention due to its benefits in thermal stability, resilience against extreme environments, low-cost manufacturing, and easy large-scale integration. , Hence, ever-increasing examples showcasing integration of oxide materials on mica have been reported, demonstrating superior performance and excellent flexibility in the oxide/mica heterostructures. − The oxide growth on mica is regarded as a form of quasi-van der Waals epitaxy (Q-vdWE) growth, wherein both van der Waals and chemical interactions bond the film layer to the substrate . Especially fascinating is the bending strain-actuated modulation of the physical properties in the flexible oxide/mica heterostructures, such as SrRuO 3 /BaTiO 3 /mica, Pr 0.5 Ca 0.5 MnO 3 /mica, and NdNiO 3 /mica, etc., showing great application potential in the fields of stretchable integrated circuits, portable electronic devices, sensor networks, and human-machine interaction devices. − …”
