Controlling Light at the Nanoscale via Novel Plasmonic Nanostructures

Plasmonics nanostructures are becoming remarkably important as tools towards manipulating photons at the nanoscale. They are poised to revolutionize a wide range of applications ranging from integrated optical circuits, photovoltaics, nano-antennas and biosensing.

Charge Transfer at the Nano Scale: Single Molecule and X-ray Photoemission Spectroscopy Measurements

Understanding and controlling electron transfer across metal/organic interfaces is of critical importance to the field of organic electronics and photovoltaics. Single molecule devices offer an ideal test bed for probing charge transfer and mechanics at these interfaces, while x-ray photoemission measurements enable a probing of femtosecond dynamics of charge transfer across interfaces.

Nanophotonic Devices, Near-field Interactions and Plasmonics at the Extreme Nanoscale

This talk will provide an overview of several nanophotonic devices with special consideration given to behind-the-scenes near-field action. Electric field magnitude mapping, as well as optical gradient force and Casimir force measurement techniques, will be reviewed as they relate to the aforementioned devices.
