"Is There Room for Bulls, Bears, and States in the Circuit?" [PDF]

This paper takes off from Jan Kregel's paper "Shylock and Hamlet, or Are There Bulls and Bears in the Circuit?" (1986), which aimed to remedy shortcomings in most expositions of the "circuit approach." While some "circuitistes" have rejected John Maynard

Hopping‐Mediated Zero‐Bias Photocharge Retention in Solution‐Processed Van Der Waals Heterostructures

Advanced Functional Materials, EarlyView.
Liquid–liquid interface assembly enables the fabrication of solution‐processed MoS2 and WSe2 centimeter‐scale, nanometer‐thick type‐II heterostructures on paper. Interfacial charge separation and hopping‐limited recombination produce rectification and persistent photocharge retention at zero bias.

Hybrid Ferroelectric Tunnel Junctions with Intrinsic Nonlinearity and Self‐Rectification via Interfacial Reconstruction

Advanced Functional Materials, EarlyView.
Rapid thermal annealing reconstructs the BCFO/Nb:STO interface into an atomically thin reconstructed interfacial layer, which reshapes the tunneling barrier and converts a high‐TER ferroelectric tunnel junction into an intrinsically nonlinear, self‐rectifying device.

Piezoelectric Energy Harvesting: Enhancing Power Output by Device Optimisation and Circuit Techniques [PDF]

, 2010
Energy harvesting; that is, harvesting small amounts of energy from environmental sources such as solar, air flow or vibrations using small-scale (≈1cm 3 ) devices, offers the prospect of powering portable electronic devices such as GPS receivers and

Nitride MXenes Beyond Carbides: Bridging the Gap Between Computational Prediction and Experimental Realization

Advanced Functional Materials, EarlyView.
Nitride MXenes remain constrained by a persistent gap between computational prediction and experimental realization. This Review identifies the thermodynamic, kinetic, and chemical barriers limiting their synthesis, critically evaluates emerging fabrication routes, and proposes a multidimensional computational‐experimental framework to accelerate the ...

Power supply for wireless devices of information measuring and control systems based on an improved piezoelectric vibration generator

Известия высших учебных заведений. Поволжский регион:Технические науки
Background. In recent years, there has been a search for alternative sources of electricity that use natural and man-made energy sources, such as solar radiation, water movement, wind, vibration and others. On an industrial scale, solar panels and wind
