Bio-interfaced Nanolaminate Surface-enhanced Raman Spectroscopy Substrates
… multiple metal-insulator-metal layers, named nanolaminate, were designed to simultaneously achieve high sensitivity and excellent uniformity, two previously deemed mutually exclusive properties. Two unique factors of nanolaminate SERS substrates were exploited for the improved reliability of …

A Nacreous Self-Assembled Nanolaminate for Corrosion Resistance on 2024-Al Alloy
Nanometer thick layers of clay and polymer were formed on mica, silicon, and aluminum 2024-T3 alloy using alternating solutions of positively and negatively charged polymer and clay, respectively. Atomic force microscopy was used to observe the morphology of the composite films on mica and silicon. …

Nanolaminate coatings to improve long-term stability of plasmonic structures in physiological environments
… plasmonic structures based on Al and Cu, nanolaminate coatings are investigated to improve their long-term stability in corrosive physiological environments. The structures are fabricated using phase-shifting PDMS masks, e-beam deposition, RIE, Atomic Layer Deposition and Rapid Thermal …

An ultrafast thermal emission spectrometer for investigating temporal thermal emission of metal thin-films and their reactive derivatives
… was constructed for studying the reaction of nanolaminate thermites in both the temporal and spectral domains. 1mJ pulses from a Ti:Sapphire laser, stretched to 10ps, were focused onto sample films affixed to glass slides. The emission generated by the ablation of the films was collected and …

Going Deeper into Laser Damage: Experiments and Methods for Characterizing Materials in High Power Laser Systems
… grown films were compared to hafnia-alumina nanolaminates. While the nanolaminates are known to perform better for 1 ns pulses, we found they had worse laser damage performance in the CW regime. We found the nanolaminates reduced crystallinity. The polycrystalline uniform films are thought to …

Multiresonant Plasmonics with Spatial Mode Overlap
… plasmonic systems. Next, we introduce the nanolaminate plasmonic crystals (NPCs), wafer-scale metamaterials structures that support many (>10) highly-excitable plasmonic modes with spatial overlap across the visible and near-infrared optical bands. The enabling factors behind the NPC's …

An evaluation of some commercially-available thin TiO2 films and TiO2 films grown by atomic layer deposition for potential photocatalytic applications
… gallium, hafnium, silver, tin and vanadium as nanolaminate dopants. The synthesized TiO2 and Ti1-xO2:Mx films provided varying photocatalytic activities dependent on differing degrees of crystalline morphology, Ti3+ concentrations and dopant used. Nominally undoped TiO2 was mainly amorphous, …

Probing Coherent States and Nonlinear Properties in Multifunctional Material Systems
… perovskite [4], n-type InAsP films [5, 6], and nanolaminate plasmonic crystals [7]. Probing multiferroics, which are materials that can exhibit ferromagnetic, ferroelectric, and ferroelastic orders simultaneously in a single phase, was a main focus of this study. BiFeO3 (BFO) is the most widely …

Multimodal Optical Interfaces Enabled by Multiresonant Plasmonics for Bio-Nanophotonics
… built on metal-insulator-metal (MIM) plasmonic nanolaminate nanopillar arrays (NLNPAs), which provide tunable multiresonant responses, nanoscale mode overlap, and an intimate bio-nano interface. For biochemical sensing, the multiband plasmonic resonances enable broadband surface-enhanced Raman …

Investigating the sink efficiencies of interfaces under irradiation
Interfaces play an important role in material properties such as strength, cracking/fracture, work hardening, corrosion, and damage evolution under irradiation and deformation. Understanding interface-defect interactions that underlie these properties is a core motivation for studying interface …
