Featured Projects
Tunable TiO2 Nanosword Plasmonic Antenna
This work focuses on integrating the nanoswords with MEMS to create a tunable plasmonic antenna for SERS detection. Efforts have begun to design a two-dimensional SOI-based actuator to mitigate the alignment issues, while in-situ SEM imaging has revealed that the nanoswords are planar. In addition, efforts have begun to use FIB to etch a plasmonic grating onto the gold-coated nanoswords to control the plasmonic resonance.
