Asymmetrical capacitor: experiments and modeling

, 2012
This research article describes experiments using several Asymmetrical Capacitors prototypes (AsC) with the objective to reproduce this unusual physical phenomenon, as well as to show its exceptional characteristics. Some results are published for the first time. The operating voltage was increased up to 31kV usinga DC generator.

Memristive‐Gated RC‐Delay Synaptic Transistors for Time‐Encoded Analog in‐Memory Computing

Advanced Functional Materials, EarlyView.
A Memristive‐Gated Transistor for Time‐Encoded Analog In‐Memory Computing — By exploiting the RC delay of a self‐rectifying interface‐type memristor, nonlinear I–V distortion is structurally bypassed, enabling 3‐bit nonvolatile memory, spike‐timing‐based analog encoding, and hardware‐calibrated reservoir‐computing validation within a unified device ...

Bacterial Cellulose‐Based Bilayer Passive Cooler for High‐Performance Radiative/Evaporative Cooling

Advanced Functional Materials, EarlyView.
A sustainable bilayer passive cooler based on bacterial cellulose integrates radiative and evaporative cooling for efficient zero‐energy temperature reduction. The scalable, low‐carbon material shows strong potential for food preservation, low‐temperature storage, and cold‐chain logistics.

Vector‐Field Control and Emergent Basal‐Plane Anisotropy of Magnetic Textures in Noncentrosymmetric (Fe0.63Ni0.3Pd0.07)3P

Advanced Functional Materials, EarlyView.
A field‐driven transition from chiral stripes to an achiral fan state is observed in a tetragonal magnet and linked to a temperature‐dependent rotation of the effective Dzyaloshinskii–Moriya interaction axis. This interplay generates pronounced in‐plane anisotropy and provides a new route for controlling chiral spin textures in noncentrosymmetric ...

Unified Phase‐Field Framework for Antiferroelectric, Ferroelectric and Dielectric Phases: Application to HZO Thin Films

Advanced Functional Materials, EarlyView.
HfxZr1−xO2${\rm Hf}_x{\rm Zr}_{1-x}{\rm O}_2$ offers CMOS‐compatible nanoscale ferroelectricity yet suffers from a high Ec${\rm E}_c$ demanding large operating voltages. A unified phase‐field framework spanning AFE/FE/DE phases shows how FE grains soften neighboring AFE grains over λ$\lambda$ ≈$\approx$ 22–37 nm.

High‐Speed Photoresponse of CVD‐Grown Lateral TMD Heterostructures

Advanced Functional Materials, EarlyView.
Internal electric fields generated by p‐n junctions and asymmetric Schottky barriers enhance the photoresponse speed in CVD‐grown monolayer TMD lateral heterostructures. This results in a 1.5‐2 orders of magnitude reduction in rise and fall times for optimized device configurations compared to homogeneous single‐material devices, enabling bandwidths ...

Bulk‐Like Spin Cycloid and Fast Switching in Freestanding BiFeO3

Advanced Functional Materials, EarlyView.
Freestanding BiFeO3 membranes overcome substrate‐induced constraints by simultaneously restoring the intrinsic bulk‐like spin cycloid and enabling ≈50% faster ferroelectric switching than substrate‐clamped epitaxial thin films. This combination of robust noncollinear antiferromagnetic order and efficient electric‐field switching establishes ...
