We fabricate a large area (3 × 3 cm2) polydimethylsiloxane-based substrate for surface-enhanced Raman scattering by combining femtosecond laser microstructuring and soft lithography techniques. The substrate exhibits broadband absorption in the region of 350–1000 nm and reproducible enhancement factor ∼107.
The high efficiency vertical light emitting diodes (V-LEDs) using mechanical lift-off with Micro-Porous GaN template formed by high temperature molten KOH wet etching process were demonstrated. The average threading dislocation density (TDD) of u-GaN after regrowth was estimated by transmission electron microscopy (TEM) reduced from 2×109 to 1×108 cm−2. The sapphire substrate was easily removed by...
We show that wetting of MgF2 films can be affected by gold films and metamaterial substrates separated from the water droplet by as much as several tens on nanometers.
We introduce a Fano resonant asymmetric ring/disk cavity system employing a conducting layer underneath. Our system shows stronger electromagnetic fields that are highly accessible to surrounding medium and sharper spectral features that result in more reliable and sensitive biodetection platforms.
We report that the angular and periodic dependence of the surface-plasmon-polaritons in gold nanodisks can be suppressed by nanorod substrates, which decreases the dipolar coupling and enhance their localization.
