Pure spin current transport in gallium doped zinc oxide [PDF]

, 2016
We study the flow of a pure spin current through zinc oxide by measuring the spin Hall magnetoresistance (SMR) in thin film trilayer samples consisting of bismuth-substituted yttrium iron garnet (Bi:YIG), gallium-doped zinc oxide (Ga:ZnO), and platinum.

Influence of an Al‐Doped ZnO Interface Layer on the Thermochromic Properties of VO2 Thin Films Deposited by RF Magnetron Sputtering

Advanced Engineering Materials, EarlyView.
Herein the metal‐to‐insulator transition is investigated when depositing vanadium dioxide (VO2) on glass or aluminum‐doped zinc oxide (AZO). O2 flow tuning during the deposition and additional post annealing are effective to control the metal‐to‐insulator transition. However, the VO2/AZO/glass stack reveals an increase in the transition temperature and

Copper Doped Zinc Oxide Nanocrystalline Thin Film: Growth, Characterization, Effect of annealing on Photocatalytic activity and electrical properties of irradiated film [PDF]

arXiv, 2018
The problem of detecting the ability of some metal oxides as photocatalysts is receiving considerable attention in the world. The studied zinc oxide is considered as one of the most utilized semiconductors, due to its direct band gap of 3.37 eV and a large exciton binding energy of 60 meV at room temperature.

Investigation of Solid‐Solution Phase Formation in AlCuNiSi Medium Entropy Alloys and its Effect on Microstructural, Thermal, and Microhardness Properties

Advanced Engineering Materials, EarlyView.
This study focuses on synthesizing equiatomic AlCuNiSi medium‐entropy alloys using mechanical alloying for advanced industrial applications. Continuous milling leads to grain refinement and the formation of stable BCC/FCC solid‐solution phases, resulting in enhanced mechanical properties. A unique Si‐rich solid‐solution phase is observed, which did not

A Study on Thermal Expansion and Thermomechanical Behavior of Composite Metal Foams

Advanced Engineering Materials, EarlyView.
The coefficient of thermal expansion of steel–steel composite metal foam (S‐S CMF) is shown to be lower than that of bulk stainless steel while its performance under compression demonstrate excellent mechanical stability and strength at all temperatures with gradualsoftening from 400 to 600 °C.

Impacts of Device Geometry and Layout on Temperature Profile during Large‐Area Photonic Curing

Advanced Engineering Materials, EarlyView.
The study investigates how gate geometry affects peak curing temperature during photonic curing of solution‐processed indium zinc oxide thin‐film transistors. Using 3D simulations and experimental validation, it reveals that larger gate areas and smaller aspect ratios increase curing temperature and thus improve transistor performance. Findings provide
