Description |
Two- and three-dimensional (2D and 3D) patterning and texturing of surfaces opens possibility to control light propagation, absorption, and scattering at nanoscale. The light-matter interaction can be spectrally tailored and enhanced using nanoparticles and their arrays. This is important for sensing applications, light harvesting in solar cells, extraction in light emitting diodes, and plasmonic nano-tweezers. Here we present recent results in high precision and fidelity fabrication of nanoparticles with resolution approaching 10 nm by combination of electron and ion beam lithographies. Surface enhanced Raman scattering (SERS) sensors based on surfaces nano-textured by laser ablation and plasma etching are demonstrated. |
