Tip‐based Lithography with a Sacrificial Layer (Small 19/2024)

Tip-Based Lithography In article number 2309484, Jae-Won Jang and co-workers report the tip-based lithography with a sacrificial layer. The sacrificial layer minimizes the scratching of the gold film by nano-indentation during tip-based lithography, which enables the fabrication of sub-50 nm-sized gold nanoholes. A single 20 nm diameter gold particle was trapped in a 35 nm diameter gold nanohole via wettability-controlled self-assembly. This structure causes strong electromagnetic wave enhancement and can be utilized in surface-enhanced Raman scattering.
