Accessing both electrochemical SEIRA and SERS with ultrasensitive metamaterials for enhanced molecular identification
Nicolas Spiesshofer, Tabitha Jones, Sarah May Sibug Torres +11
Surface-enhanced IR absorption (SEIRA) and surface-enhanced Raman spectroscopy (SERS) are complementary techniques that allow for ultrasensitive chemical fingerprinting. Non-invasi…
Extreme mid-infrared field enhancement and anapoles in high-index plasmonic metamaterials
Zoltan Sztranyovszky, Nicolas Spiesshofer, Caleb Todd +5
High-refractive-index materials underpin a wide range of optical technologies, including communications, imaging, lasers, and integrated photonic systems. Here, we demonstrate a se…
Coherent room-temperature dipole synchronization in nanocavity sheets
Rakesh Arul, Piper Fowler-Wright, Lille Borresen +3
Plasmonic nanocavities enable the synchronization of spatially distant emissive dipoles through strong near-field coupling in sub-nm gaps. We report formation of a room-temperature…
Migration of gold atoms into a thiol-bonded molecular self-assembled monolayer, forming a cluster exhibiting a Coulomb staircase
Bingxin Li, Shanglong Ning, Chunyang Miao +16
Thiol-based self-assembled monolayers (SAMs) on gold surfaces are one of the fundamental building blocks of molecular electronics. The strong chemical affinity of the gold and sulf…
Tracking and controlling monolayer water in gold nanogaps using extreme plasmonic spectroscopy
Elle W. Wyatt, Sarah May Sibug-Torres, Rakesh Arul +5
Nanogaps are ubiquitous across science, confining molecules and thus changing chemistries which influence many areas such as catalysis, corrosion, photochemistry, and sensing. Howe…
Uncovering low-frequency vibrations in surface-enhanced Raman of organic molecules
Alexandra Boehmke, Roberto A Boto, Eoin Elliot +7
Accessing the terahertz (THz) spectral domain through surface-enhanced Raman spectroscopy (SERS) is challenging and opens up the study of low-frequency molecular and electronic exc…
Direct Linearly-Polarised Electroluminescence from Perovskite Nanoplatelet Superlattices
Junzhi Ye, Aobo Ren, Linjie Dai +26
Polarised light is critical for a wide range of applications, but is usually generated by filtering unpolarised light, which leads to significant energy losses and requires additio…
Magneto-optical coupling in whispering gallery mode resonators
J. A. Haigh, S. Langenfeld, N. J. Lambert +4
We demonstrate that yttrium iron garnet microspheres support optical whispering gallery modes similar to those in non-magnetic dielectric materials. The direction of the ferromagne…
