A New Threshold Switching Device With Tunable Negative Differential Resistance Based on ErMnO3 Polymorphs

Advanced Functional Materials, EarlyView.
Polymorph engineering in ErMnO3 enables low‐voltage, forming‐free threshold switching with tunable negative differential resistance. Conducting orthorhombic regions embedded in an insulating hexagonal matrix provide controlled Joule‐heating‐enhanced Poole–Frenkel transport. The hexagonal phase prevents excessive heating and breakdown.

Overcoming Debye Length Limitations in Electrolyte‐Gated Transistor Biosensors Using Nanoscale‐Grooved Oxide Semiconductors Fabricated by Thermal Nanoimprint Lithography

Advanced Functional Materials, EarlyView.
Nanoscale‐grooved indium gallium oxide (IGO) semiconductors, patterned via thermal nanoimprint lithography (NIL) using CD/DVD templates, are integrated into electrolyte‐gated transistor biosensors to overcome Debye length limitations. Precisely engineered concave–convex nanostructures modulate local electrostatic potentials, extend the effective Debye ...

Color Routing and Beam Steering of Single‐Molecule Emission with a Spherical Silicon Nanoantenna

Advanced Functional Materials, EarlyView.
We experimentally demonstrate broadband directional emission from single molecules using a single spherical silicon nanoparticle assembled via DNA origami. By varying nanoparticle (NP) size and emitter position, we achieve unidirectional emission, beam steering, and color routing at the nanoscale, revealing modal interference as the underlying ...

Non-Invasive Multidimensional Capacitive Sensing for In Vivo Traumatic Brain Injury Monitoring. [PDF]

Adv Mater Technol
Single‐electrode, multidimensional capacitive sensors noninvasively assess cerebral autoregulation and compliance for traumatic brain injury monitoring. ABSTRACT Traumatic brain injury (TBI) is a major cause of death and disability, but invasive intracranial pressure (ICP) monitoring is risky, and current non‐invasive methods lack the resolution and ...
