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

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

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 ...

A Single Sub-Millimetric Metasurface-Based Optical Element for Lattice Bessel Beam Excitation Enabling Brain Activity Recordings In Vivo

Giulia Tagliabue, Anna Archetti

Bessel beams (BBs) are propagation-invariant optical fields that retain a narrow central intensity profile over longer propagation lengths than Gaussian beams (GBs). Due to this property, they have been adopted in fluorescence-based light sheet microscopy ...

Hydrogel-based thermoelectrochemical cells for waste heat recovery under passive cooling conditions

Giulia Tagliabue, Matteo Bevione

Hydrogel-based thermoelectrochemical cells sustain large temperature gradients under passive cooling, producing up to 35 mW m−2 and a 3.5 mV K−1 Seebeck response. They are robust across orientations, enabling scalable waste-heat recovery. ...

Large-area Monocrystalline Copper Microflake Synthesis

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

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 ...

Re-defining Non-tracking Solar Cell Efficiency Limits with Directional Spectral Filters

Giulia Tagliabue, Alan Richard Bowman

Optical filters that respond to the wavelength and direction of incident light can be used to increase the efficiency of tracking solar cells. However, as tracking solar cells are more expensive to install and maintain, it is likely that nontracking solar ...

Best practices in measuring absorption at the macro- and microscale

Giulia Tagliabue, Alan Richard Bowman, Fateme Kiani Shahvandi, Jiaming Ma

The fraction of light absorbed in a material is a key parameter for a wide range of optoelectronic and energy devices, including solar cells, light emitting diodes, and photo(electro)chemical devices. It can reveal detailed performance information and esta ...

Spatially resolved photoluminescence analysis of the role of Se in CdSexTe1−x thin films

Giulia Tagliabue, Alan Richard Bowman

Evidence from cross-sectional electron microscopy has previously shown that Se passivates defects in CdSexTe1−x solar cells, and that this is the reason for better lifetimes and voltages in these devices. Here, we utilise spatially resolved photoluminescen ...
