Decoupling Optical and Thermal Dynamics in Dielectric Metasurfaces for Self-Encoded Photonic Control

Giulia Tagliabue, Elif Nur Dayi, Omer Can Karaman, Alan Richard Bowman

Thermo-optical nonlinearities (TONL) in metasurfaces enable dynamic control of optical properties—such as transmitted power, phase, and polarization—through external stimuli like laser irradiation or temperature. Due to the inherently slow thermal dynamics ...

Large-area Monocrystalline Copper Microflake Synthesis

Giulia Tagliabue, Elif Nur Dayi, Omer Can Karaman, Alan Richard Bowman

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. However, existing synthesis methods are limited with many undesirable byprodu ...

Periodic and Aperiodic NiFe Nanomagnet/Ferrimagnet Hybrid Structures for 2D Magnon Steering and Interferometry with High Extinction Ratio

Dirk Grundler, Vinayak Shantaram Bhat, Sho Watanabe, Andrea Mucchietto, Shixuan Shan, Elif Nur Dayi

Magnons, quanta of spin waves, are known to enable information processing with low power consumption at the nanoscale. So far, however, experimentally realized half-adders, wave-logic and binary output operations were based on few µm-long spin waves and re ...

TaOx electron transport layers for CO2 reduction Si photocathodes

Raphaël François Lemerle, Elif Nur Dayi

Electron transport layers (ETLs) used as components of photocathodes for light-driven CO2 reduction (CO2R) in aqueous media should have good electronic transport, be stable under CO2R conditions, and, ideally, be catalytically inert for the competing hydro ...

Selective area epitaxy of GaAs: the unintuitive role of feature size and pitch

Anna Fontcuberta i Morral, Lucas Güniat, Martin George Friedl, Nicholas Paul Morgan, Akshay Balgarkashi, Didem Dede, Elif Nur Dayi, Valerio Piazza, Vladimir Dubrovskii

Selective area epitaxy (SAE) provides the path for scalable fabrication of semiconductor nanostructures in a device-compatible configuration. In the current paradigm, SAE is understood as localized epitaxy, and is modelled by combining planar and self-asse ...
