Interfacial Control of Degradation Pathways in 2D Heterostructures
Advanced Functional Materials, EarlyView.The stability of two‐dimensional (2D) heterostructures is governed not only by their intrinsic chemistry but also by interfacial effects. This study reveals how metallic versus insulating substrates impact the oxidation of air‐sensitive 2H‐MoTe2. Metallic layers act as charge reservoirs, mitigating degradation, while insulating ones accelerate it ...

Near‐Sensor Analog Computing via Monolithic 3D Piezoelectric Sensor–FeFET for Tactile Sensing System
Advanced Functional Materials, EarlyView.A monolithic 3D‐integrated tactile system combines a piezoelectric sensor and ferroelectric field‐effect transistor (FeFET) to process both static and dynamic pressure signals directly at the sensor node. The system enables in‐sensor analog noise filtering with multi‐level memory states, achieving high sensitivity and ultra‐low power operation (≈10 nW),

Optimization techniques for permittivity and permeability determination
Journal of Research of the National Institute of Standards and Technology, 1991 This paper discusses optimization techniques for the determination of complex permittivity and permeability in transmission lines. The traditional theoretical model using scattering parameters is extended into a mathematical regression model that can be solved with widely accepted numerical techniques.

Growth of Millimeter‐Sized BaTaO2N Single Crystals by an NH3‐Assisted BaCl2 Flux Method
Advanced Functional Materials, EarlyView.Millimeter‐sized BaTaO2N single crystals are successfully grown from a BaCl2 flux under NH3 flow. Their comprehensive characterization, including dielectric properties, is demonstrated, and the possible growth mechanisms are discussed. Abstract Perovskite‐type oxynitrides have attracted considerable attention due to their excellent photocatalytic ...
