Precision-Crafted Nanometer-Scale Gaps in Au Electrodes via Microtomy for Next-Generation Nanochannel Devices

This study introduces a cutting-edge microtomy-based approach to fabricate nanometer-precise gaps between gold (Au) electrodes, enabling the creation of advanced nanochannel and nanogap components. By leveraging supramolecular multilayered templates, we achieve unparalleled control over gap dimensions, reaching sub-nanometer accuracy. This technique outperforms traditional fabrication methods, offering exceptional reproducibility and structural fidelity. The resulting nanogaps exhibit optimized electrical and mechanical properties, making them ideal for integration into next-generation devices such as ultrasensitive sensors, quantum tunneling junctions, and molecular-scale electronics. Our method’s scalability and precision pave the way for transformative applications in nanotechnology, redefining the boundaries of device miniaturization and performance.
