Diamond Metasurface‐Based Optical Tweezers With Enhanced Robustness

open access: yesAdvanced Science, EarlyView.
Conventional metasurface optical tweezers are hindered by thermal instability from laser heating. This work overcomes this by using diamond metasurfaces, exploiting their low thermo‐optic coefficient and minimal thermal expansion. The platform demonstrates stable particle trapping, translocation, and rotation, enabling robust miniaturized systems for ...

Improved Direct Ink Writing of Liquid Metal Foams via Liquid Additives

open access: yesAdvanced Electronic Materials, EarlyView.
The ability to pattern liquid metal is useful for making soft electrical and thermal devices. Dispensing liquid metal from a nozzle naturally results in the formation of spheroidal droplets, making direct‐write printing challenging. Liquid metal foams containing pockets of air can extrude as filaments, albeit inconsistently.

Pinch‐Off Mechanism of High‐Gain Organic Transistors with Field Plates: Statistical Analysis, Device Simulations and Compact Modeling

open access: yesAdvanced Electronic Materials, EarlyView.
Statistical analysis of over 3000 devices reveals a novel operating mechanism in printed organic thin‐film transistors featuring a grounded field plate beneath the source. The field plate governs the low and tunable pinch‐off, enabling excellent current saturation and ultra‐high gain.

Lattice Dynamics of Rutile Germanium Dioxide (r‐GeO2)

open access: yesAdvanced Electronic Materials, EarlyView.
The rutile polymorph of GeO2 is a promising ultra‐wide bandgap material, but key properties for its technological exploitation remain poorly understood. Using polarization angle‐resolved Raman spectroscopy, we resolve long‐standing uncertainties in the energies of Raman‐active phonons and extract relative Raman tensor elements.

Stretchable Energy Storage with Eutectic Gallium Indium Alloy

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
A highly stretchable liquid metal‐based electrode is developed via a one‐step process, retaining conductivity and capacitance after mechanical deformation up to 900% strain. The stretchable all‐solid‐state device provides a areal energy density of 43 µWh cm⁻2 after 150% strain.
