Metaphotonic Catalysis: Amorphous silicon metasurfaces encode photochemical activity
Elif Nur Dayi, Priscila Vensaus, Milad Sabzehparvar +3
Solar-to-fuel conversion can benefit from photoelectrodes with engineered light-matter interactions, yet most nanostructured designs provide limited control over the spatial and sp…
Revealing Wavelength- and Size-Dependent CO2 Reduction Selectivity via Operando Scanning Photo-Electrochemical Microscopy
Fatemeh Kiani, Milad Sabzehparvar, Priscila Vensaus +6
Controlling product selectivity in plasmonic catalysis, particularly in CO2 reduction (CO2R), remains a central unsolved challenge with direct implications for light-driven fuel an…
Photo-Thermally Tunable Photon-Pair Generation in Dielectric Metasurfaces
Omer Can Karaman, Hua Li, Elif Nur Dayi +2
Photon-pair sources based on spontaneous four-wave mixing (SFWM) in integrated photonics are often spectrally static. We demonstrate and model a fundamental thermo-optical mechanis…
Cross-polarized and Stable Second Harmonic Generation from Monocrystalline Copper
Elif Nur Dayi, Alan R. Bowman, Omer Can Karaman +2
Second-harmonic generation (SHG) is a powerful surface-specific probe for centrosymmetric materials, with broad relevance to energy and biological interfaces. Plasmonic nanomateria…
Large area monocrystalline and surfactant-free copper microflake synthesis
Elif Nur Dayi, Diotime Pellet, Priscila Vensaus +4
Copper is one of the most extensively studied materials for energy conversion and catalytic systems, with a wide range of other applications from nanophotonics to biotechnology. Ho…
