Strategies for employing nano-heterostructures in a near-field enhanced super-resolution optical disk

摘要

Functional nano-heterostructures are of great interests in nano-photonics applications. A new strategy to obtain local nano-heterostucture formed by laser-induced eutectic transition is proposed in this paper. Numerical simulations demonstrate that periodic eutectic microstructures formed on binary eutectic alloy thin film during irradiation of a laser beam can result in a prominent near-field enhancement. Results can help to understand the microscopic mechanism of eutectic-binary-alloy-type super-RENS disk from a near-field optics view.
