Gradient High-Q Dielectric Metasurfaces for Broadband Sensing and Control of Vibrational Light-Matter Coupling

Hatice Altug, Aleksandrs Leitis, Felix Ulrich Brikh, Ivan Sinev, Senlu Zhou

Surface-enhanced infrared absorption spectroscopy (SEIRA) has emerged as a powerful technique for ultrasensitive chemical-specific analysis. SEIRA can be realized by employing metasurfaces that can enhance light-matter interactions in the spectral bands of ...

Tuning the response of non-allowed Raman modes in GaAs nanowires

Anna Fontcuberta i Morral, Gözde Tütüncüoglu, Federico Matteini, Esther Alarcon Llado, Emanuele Uccelli, Francesca Amaduzzi

We report on the use of photonic resonances in Raman spectroscopy on single nanowires for the enhancement of forbidden modes and the study of the interaction of phonons with free-carriers. This is achieved by suspending nanowire over a trench and detecting ...

Analysis of composition homogeneity and polarization orientation of PZT submicron fibers by micro-Raman spectroscopy

Nava Setter, Silviu Cosmin Sandu, Jin Wang

Micro-Raman spectroscopy is a convenient tool to probe individual objects with a feature size on the submicron scale. The phase, composition, and orientation of Pb(Zr,Ti)O-3 fibers fabricated via hydrothermal processing have been characterized by this tech ...

Orbital selective overlayer-substrate hybridization in a Pb monolayer on Ag(111)

Klaus Kern, Frédéric Mila, Harald Brune, Marco Grioni, Thomas Gloor, Stephan Fedrigo

The electronic structure of a Pb overlayer on Ag(111) has been studied by angle-resolved photoemission spectroscopy. We identify three p bands. While the p(xy) bands are sharp and closely resemble the corresponding bands of a free-standing Pb layer, the p( ...
