Toward Rapid Low‐Cost Fabrication of Single‐Nanowire Photodetectors via the Utilization of Dielectrophoresis

Advanced Photonics Research, EarlyView.
A scalable, low‐cost approach for assembling single germanium nanowires (NWs) into photodetectors is demonstrated using a modified dielectrophoresis method with a voltage‐divider circuit. This self‐limiting assembly technique achieves ultrahigh responsivity (>6 × 105 A W−1) at 700 and 1550 nm without requiring nanoscale electrodes, offering a versatile

Integration of Soft‐Robotics and Deep Learning to Assess the Coordinated Biosonar Emission and Reception Dynamics in Hipposiderid Bats

Advanced Robotics Research, EarlyView.
Combining a biomimetic soft‐robot with deep‐learning data analytics sheds light on a unique peripheral dynamics seen in the biosonar system of bats: Bats modulate their ultrasonic biosonar signals upon emission as well as reception with variable, yet highly coordinated motion patterns of their noseleaves and pinnae.

Observation of Localized Resonant Phonon Polaritons in Biaxial α‐MoO3 Nanoparticles

Advanced Science, EarlyView.
Biaxial α‐MoO3 nanoparticles exhibit tunable, high‐Q mid‐infrared resonances driven by localized phonon polaritons. Combining a novel synthesis method, hyperspectral near‐field imaging and a unified theoretical analysis, this work reveals eigenmodes and resonance conditions in biaxial particles.
