High‐Power Terahertz Emission from Picosecond Nano‐Plasma Switching Driven by Secondary Electron Emission Avalanche

open access: yesAdvanced Science, EarlyView.
A nano‐plasma device enables watt‐level on‐chip THz generation through picosecond switching triggered by secondary electron emission avalanche. An ultra‐dense electron sheet initiates nano‐plasma formation within a ∼100 nm gap, driving rapid energy release into an integrated resonator.

A Dual‐Channel Synergistic Ultrasensitive Biosensor for Tumor Liquid Biopsy

open access: yesAdvanced Science, EarlyView.
ABSTRACT Liquid biopsy technology, which detects circulating tumor DNA (ctDNA) in cerebrospinal fluid, plays a crucial role in the early diagnosis and precision treatment of gliomas. However, the intrinsically low abundance and rapid clearance of ctDNA pose substantial challenges for conventional analytical techniques, such as droplet digital PCR and ...

Extreme‐Thickness Meta‐Membrane for Controlling Terahertz Vectorial Beams

open access: yesAdvanced Science, EarlyView.
We propose ultra‐thin (λ/30) transmissive terahertz metasurfaces combining near‐field resonant and detour phases in coupled‐slit meta‐atoms, enabling continuous phase and polarization control beyond conventional designs. Based on leaky‐mode theory, scalar and vectorial terahertz Bessel beams at 0.39 THz are experimentally demonstrated, with ...

Field‐Frustrated Cooperative Distortions: Suppressing Jahn‐Teller Ordering via Microwave Annealing

open access: yesAdvanced Science, EarlyView.
Microwave annealing decouples local Jahn‐Teller distortions from long‐range cooperative ordering in CuFe2O4, stabilizing a metastable cubic phase that remains locally distorted yet globally symmetry‐frustrated. Synchrotron XRD, PDF, XPS, and in situ thermal cycling reveal how non‐equilibrium MW‐phonon interactions suppress cooperative orbital‐lattice ...
