Two-terminal resistive switches based on vanadium dioxide are considered as promising functional devices in oxide electronics. However, resistive switches based on polycrystalline films cannot withstand long-term switching cycles. In this work, we propose a novel heterostructures of vanadium dioxide thin films synthesized on vertically oriented mazy-like boron carbonitride nanowalls. A resistance jump of more than three orders of magnitude during the temperature phase transition in vanadium dioxide was obtained for all formed structures. We demonstrated that vanadium dioxide films grown on vertical nanowalls exhibit a more than two orders of magnitude higher number of stable resistive switches, compared to films synthesized on well-studied silicon substrates. The number of stable switching increases from 4 × 107 to 2 × 109 with the increasing height of boron carbon nitride nanowalls from 50 to 400 nm. The studies suggest that the proposed heterostructures are promising for the development of stable and long-life functional electronic and optoelectronic devices.
