Rotary 4D Printing of Programmable Metamaterials on Sustainable 4D Mandrel

open access: yesAdvanced Materials Technologies, EarlyView.
The paper introduces open, rotary 4D printing of programmable tubular metamaterials. It presents an open, non‐planar path‐to‐G‐code pipeline and shape‐changing rotary mandrel that enable support‐free fabrication and multi‐stimuli actuation. Experiments and FEA validate the mentioned features and stress redistribution.

Understanding and Circumventing Failure Mechanisms in Chalcogenide Optical Phase Change Material Ge2Sb2Se4Te

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Chalcogenide optical PCMs have gathered interest for their potential in compact, non‐volatile optics and photonics. Free‐space PCM metasurfaces require new considerations from phase change memory that need to be addressed for reliable scale‐up. Several failure mechanisms pertaining to free‐space PCM devices and layout methods are isolated to prevent ...

High‐Resolution Electron‐Beam Poling of X‐Cut Lithium Niobate Thin Films

open access: yesAdvanced Optical Materials, EarlyView.
A new periodic poling technique using electron beams to create stable, high‐quality ferroelectric patterns is developed in x‐cut thin‐film lithium niobate (TFLN). The method works at room temperature with both standard and MgO‐doped materials, affords ferroelectric domain pitches as small as 375 nm, and lends itself to seamless integration with state ...
