Metal-Dielectric-Metal Resonators with Deep Subwavelength Dielectric Layers Increase the Near-Field SEIRA Enhancement

September 24, 2015

Author(s)

Jungseok Chae, Basudev Lahiri, John M. Kohoutek, Glenn Holland, Henri Lezec, Andrea Centrone

Plasmonic nanostructures presenting either structural asymmetry or metal-dielectric-metal (M-D-M) architecture are commonly used structures to increase the quality factor and the near-field confinement in plasmonic materials. This characteristic can be

Absorption spectroscopy and imaging from the visible through mid-infrared with 20 nm resolution.

March 17, 2015

Author(s)

Aaron M. Katzenmeyer, Glenn Holland, Kevin Kjoller, Andrea Centrone

Absorption spectroscopy and mapping from visible through mid-IR wavelengths has been achieved with spatial resolution exceeding the limit imposed by diffraction, via the photothermal induced resonance technique. Correlated vibrational (chemical), and

Near-Field Asymmetries in Plasmonic Resonators

February 12, 2015

Author(s)

Vladimir Aksyuk, Basudev Lahiri, Glenn Holland, Andrea Centrone

Surface-enhanced infrared absorption (SEIRA) spectroscopy exploits the locally enhanced field surrounding plasmonic metamaterials to increase the sensitivity of infrared spectroscopy. Light polarization and incident angle are important factors for exciting

Nanoscale Imaging and Spectroscopy of Plasmonic Modes with the PTIR technique

August 1, 2014

Author(s)

Aaron M. Katzenmeyer, Jungseok Chae, Richard Kasica, Glenn Holland, Basudev Lahiri, Andrea Centrone

The collective oscillation of conduction electrons in plasmonic nanomaterials allows the coupling of propagating light waves with nanoscale volumes of matter ("hot spots") and allows engineering their optical response from the UV to THz as a function of

Assessing Chemical Heterogeneity at the Nanoscale in Mixed-Ligand Metal-Organic Frameworks with the PTIR Technique

March 10, 2014

Author(s)

Aaron M. Katzenmeyer, Jerome Canivet, Glenn Holland, David Farrusseng, Andrea Centrone

Metal-organic frameworks (MOFs), are crystalline, micro to mesoporous functional materials consisting of inorganic clusters interconnected by organic linkers. The possibility of tailoring the chemical functionality and pore size while maintaining the

Nanoscale Imaging of Plasmonic Hot Spots and Dark Modes with the Photothermal Induced Resonance Technique

July 10, 2013

Author(s)

Basudev Lahiri, Glenn E. Holland, Vladimir A. Aksyuk, Andrea Centrone

The collective oscillation of conduction electrons, responsible for the LSPRs, enables engineering nanomaterials by tuning their optical response from the visible to THz as a function of nanostructure size, shape and environment. While theoretical

Chemical imaging beyond the diffraction limit using photothermal induced resonance microscopy

April 2, 2013

Author(s)

Andrea Centrone, Basudev Lahiri, Glenn E. Holland

Photo Thermal Induced Resonance (PTIR), recently attracted great interest for enabling chemical identification and imaging with nanoscale resolution. In this paper, the PTIR working principles are reviewed along the main results from a recent publication

Chemical Imaging Beyond the Diffraction Limit: Experimental Validation of the PTIR Technique

February 11, 2013

Author(s)

Basudev Lahiri, Glenn Holland, Andrea Centrone

Photo Thermal Induced Resonance (PTIR), recently attracted great interest for enabling chemical identification and imaging with nanoscale resolution. In this work, electron beam nano-patterned polymer samples were fabricated directly on 3-dimentional zinc
