Spatially Encoded Polaritonic Ultra‐Strong Coupling in Gradient Metasurfaces with Epsilon‐Near‐Zero Modes

open access: yesAdvanced Materials, EarlyView.
Dielectric dual gradient metasurfaces supporting quasi‐bound‐states‐in‐the‐continuum are leveraged to spatially encode both the spectral and coupling parameter space and demonstrate ultra‐strong coupling to an epsilon‐near‐zero mode in an ultra‐thin SiO2 layer.The platform achieves exceptional mode overlap, reaching a normalized coupling strength of η =

Bifunctionally Driven Organic Photonic Conversion Devices Facilitated by Minimalistic Synthesis‐Based Interfacial Energetic Alignment

open access: yesAdvanced Materials, EarlyView.
A benzene‐phosphonic acid self‐assembled monolayer (BPA) simultaneously optimizes hole extraction and noise suppression, enabling bifunctional organic photovoltaics–photodetectors that deliver superb indoor performance and commercial viability. BPA‐devices achieve 28.6% PCE at 1000 lx, retain 93% efficiency on large‐scaled devices, and reach 584 fW NEP

Size‐Dependent Contact Angles of Microscopic Droplets on Ultra‐Smooth Silanized Surfaces Probed by Atomic Force Microscopy

open access: yesAdvanced Materials Interfaces, EarlyView.
Wetting is vital in many technologies, but remains hard to predict due to complex phase interactions. Young's law predicts macroscale wetting on ideal surfaces, while line tension theory is limited to nanoscale droplets. Here, using AFM, the scale gap is bridged by focusing on microscopic droplets and predicting their contact angle on real surfaces ...

Influence of Micropillar Height Modulation on Droplet Evaporation and Wetting State Transitions

open access: yesAdvanced Materials Interfaces, EarlyView.
Controlling droplet evaporation dynamics is crucial across many fields. Here, it demonstrates laser‐fabricated polymer micropillar arrays with tailored height variations to regulate evaporation behavior. While all arrays exhibit superhydrophobic wetting, their distinct height profiles effectively slow evaporation and alter evaporation modes ...
