Enhancing Direct Solar Water Splitting via ALD of Multifunctional TiO2/Pt Nanoparticle Coatings With Engineered Interfaces to GaAs/GaInP Tandem Cells

Advanced Functional Materials, EarlyView.
Multifunctional atomic layer deposited coatings and interface treatments enhance direct solar water splitting on GaAs/GaInP tandem cells. Optimized TiO2/Pt nanoparticle bilayers ensure durability and catalytic efficiency with minimal optical losses, while H2 plasma pretreatments maximize photovoltage and interfacial charge extraction.

Prospects of Electric Field Control in Perpendicular Magnetic Tunnel Junctions and Emerging 2D Spintronics for Ultralow Energy Memory and Logic Devices

Advanced Functional Materials, EarlyView.
Electric control of magnetic tunnel junctions offers a path to drastically reduce the energy requirements of the device. Electric field control of magnetization can be realized in a multitude of ways. These mechanisms can be integrated into existing spintronic devices to further reduce the operational energy.

Corrections to the universal behavior of the Coulomb-blockade peak splitting for quantum dots separated by a finite barrier

, 1996
Building upon earlier work on the relation between the dimensionless interdot channel conductance g and the fractional Coulomb-blockade peak splitting f for two electrostatically equivalent dots, we calculate the leading correction that results from an ...

Quantum well width and barrier Thickness effects on the perpendicular transport in polar and non-polar oriented AlGaN/GaN Resonant Tunneling Diodes

2021 IEEE International Conference on Design & Test of Integrated Micro & Nano-Systems (DTS), 2021
In this study, we theoretically investigated the electronic properties of resonant tunneling diodes (RTDs) grown along the polar and non-polar orientations by using the self-consistent solution of the coupled Schrödinger and Poisson equations. Based on the transfer matrix formalism, the effects of the geometrical parameters on the current-voltage ...

Electron tunneling through barriers of adjustable width: Role of the image potential and the wetting behavior of Cs by He [PDF]

Physical Review B, 2008
Photocurrents from cesium, flowing through gaseous 3 He or 4 He and also through thin liquid helium films, are investigated as a function of the chemical potential of helium at T = 1.33 K. At low pressures, the two isotopes behave similarly as the photocurrent is governed by scattering by the gas. At higher pressures, a film of 3 He grows on the Cs and

Extremely Elevated Room-Temperature Kinetic Isotope Effects Quantify the Critical Role of Barrier Width in Enzymatic C–H Activation

Journal of the American Chemical Society, 2014
The enzyme soybean lipoxygenase (SLO) has served as a prototype for hydrogen-tunneling reactions, as a result of its unusual kinetic isotope effects (KIEs) and their temperature dependencies.
