All-Dielectric Photo-thermo-optical Metasurfaces for Thermal Landscaping at the Nanoscale
Gopal Narmada Naidu, Omer Can Karaman, Giulia Tagliabue
Precise control of temperature fields at the micro- and nanoscale is essential for emerging applications in nanophotonics, catalysis, and microfluidics, yet remains difficult due t…
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…
Thin-wall Single-crystal Gold Nanoelectrodes towards Advanced Chemical Probing and Imaging
Milad Sabzehparvar, Fatemeh Kiani, Germán García Martínez +4
Thin-wall metal ultramicro- and nanoelectrodes (UMEs/NEs), especially gold NEs, are indispensable for high-resolution electrochemical microscopy, biosensing, and fundamental resear…
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…
Decoupling Optical and Thermal Responses: Thermo-optical Nonlinearities Unlock MHz Transmission Modulation in Dielectric Metasurfaces
Omer Can Karaman, Gopal Narmada Naidu, Alan R. Bowman +2
Thermo-optical nonlinearities (TONL) in metasurfaces enable dynamic control of optical properties like transmission, reflection, and absorption through external stimuli such as las…
