Integrated plasmonic nano-antenna devices
… devices. An example of a plasmonic device is a nano-antenna. Although nano-antennas are applied in biological sensing, imaging and nano-particle manipulations, they are passive devices that must be driven by an external source. As combining plasmonic nano-antennas with micro-lasers is the main …

Electronic and Plasmonic Properties of Nano-Sized Gold/Strontium Titanate Interface
In this thesis, nano-sized metal/oxide interfaces are fabricated to determine the size dependence of electronic and resistive switching properties, effect of atomic structure on the orientation dependence of electronic properties, and mechanisms of plasmon-induced current enhancement. A combination …

Nonlinear optical emission and near-field enhancement effects in arrays of gold bowtie nano-antennas
… enhancements from periodic arrays of gold bowtie nano-antennas (BNAs) after illumination by laser light. Specifically, we focus on laser-induced damage, nonlinear optical emission, and a proof-of-concept for utilizing arrays of gold BNAs to enhance the forces in an optical trapping system. From …
