Erosion Corrosion Evaluation of CrN/AlN Multilayer Coatings, by Varying the Velocity and Impact Angle of the Particle

International Journal of Electrochemical Science, 2013
In order to provide solutions to erosion corrosion in industrial devices, thin films of CrN/AlN were deposited on AISI D3 steel substrates using a magnetron sputtering system multitarget with rf (13.56 MHz), from Al and Cr targets of high purity (99.99%)

Sub‐Nanometer Curvature Unlocks Quantum Orbital Flexoelectricity in Graphene

Advanced Materials, EarlyView.
In self‐assembled, reproducible, large‐area, quasi‐pristine graphene nanowrinkles, extreme curvature forces out‐of‐plane π‐electrons toward hybridization, driving a transition from classical to quantum orbital flexoelectricity. As curvature approaches the fundamental physical limit set by the C─C bond length, the resulting polarization increases by ...

Proximity Ferroelectricity in Compositionally Graded Structures

Advanced Electronic Materials
Proximity ferroelectricity is a novel paradigm for inducing ferroelectricity in a non‐ferroelectric polar material, such as AlN or ZnO that are typically unswitchable with an external field below their dielectric breakdown field.

LEAD: Literature Enhanced Ab Initio Discovery of Nitride Dusting Layers for Enhanced Tunnel Magnetoresistance and Lower Resistance Magnetic Tunnel Junctions

Advanced Materials, EarlyView.
Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

Сlarification of the state diagram of “Metal 1-Metal 2” systems by analyzing the “cloud” of data of combustion parameters of “Metal 1-Metal 2-Nitrogen” SHS systems

Қарағанды университетінің хабаршысы. Физика сериясы
The combustion of the “Metal 1 — Metal 2 — Nitrogen” systems in the layer-by-layer mode of self- propagating high-temperature synthesis was studied. A large amount of experimental data was obtained by changing the initial synthesis parameters.

Signatures of Edge States in Antiferromagnetic Van der Waals Josephson Junctions

Advanced Materials, EarlyView.
ABSTRACT The combination of superconductivity and magnetic textures leads to unconventional superconducting phenomena, including new correlated and topological phases. Van der Waals (vdW) materials emerge as a versatile platform for exploring the interplay between these two competing orders.

Generating Unconventional Spin‐Orbit Torques With Patterned Phase Gradients in Tungsten Thin Films

Advanced Materials, EarlyView.
ABSTRACT A key aim in spintronics is to achieve current‐induced magnetization switching via spin‐orbit torques without external magnetic fields. For this, the focus of recent work has been on introducing controlled lateral gradients across ferromagnet/heavy‐metal devices, giving variations in thickness, composition, or interface quality.
