Study of the bowing parameter and Urbach edge in AlGaN alloys grown by plasma-assisted molecular beam epitaxy
Optoelectronic devices based on AlGaN alloys find a wide range of applications, such as water and surface purification, solar-blind photodetection, and skincare. The energy bandgap of the alloy is a c...
The point pinning centers and critical current density in NbTi wires
The results of this work show that annealing under 0.4 GPa isostatic pressure does not influence the critical temperature (Tc) of the NbTi wire, which is about 9 K. Moreover, our studies indicate that...
Perfect sound absorption induced by topological acoustic unidirectional guided resonance
Perfect sound absorption (PSA) plays a vital role in various acoustic applications. Acoustic unidirectional guiding resonances (AUGRs) are a novel class of topologically enabled guided resonance that...
Bridging material models across scales: An integrated approach to equation of state and molecular dynamics modeling of copper
New uncertainty-aware equation of state (EOS) and electrical conductivity (EC) models for copper have been developed. The multiphase EOS/EC models are fit to experimental solid/liquid EC isobar measur...
Architecture of 3D magnetic domain wall memory for suppressing bit-shift error
We propose an architecture for the suppression of magnetic domain wall shift error in 3D magnetic domain wall memory, which utilizes the spatially modulated perpendicular magnetic anisotropy (PMA) of...
Fe lattice sites, charge states, and spin dynamics in In0.10Ga0.90N following 57Mn+ implantation
The lattice locations and charge states of dopants in a crystal structure influence the optical, electronic, or magnetic properties of doped semiconductors. In this study, Fe lattice sites and charge...
Impact of interfacial termination on L10-MnAl spin torque perpendicular magnetic tunnel junctions: A DFT-NEGF study
L 1 0 -ordered MnAl is a promising material for designing perpendicular magnetic tunnel junctions (MTJs), thanks to its unique properties, such as high bulk perpendicular magnetic anisotropy, thermal...
Refined physical model for understanding the secondary electron doping contrast mechanism
This paper explores the use of secondary electron (SE) doping contrast in scanning electron microscopy (SEM) for visualizing and quantifying doping in silicon carbide (SiC), a vital wide bandgap semic...
Induction of large in-plane uniaxial magnetic anisotropy for Co–Fe–B–Pt thin films by magnetic field annealing
We report the induction of large in-plane uniaxial magnetic anisotropy for the CoFeB-based thin films by post-annealing under the magnetic field application. The comprehensive study reveals the influe...
Tip-enhanced superconductivity in titanium
We report a substantial enhancement of the superconducting transition temperature (Tc) in elemental titanium through mesoscopic point-contact formation using a simple needle–anvil technique. While bul...
Room temperature operation of Ge/Si <i>x</i> Ge1− <i>x</i> − <i>y</i> Sn <i>y</i> terahertz quantum cascade lasers predicted using extended combined resonant tunneling and rate equation model
Raising operation temperature of terahertz (THz) quantum cascade lasers (QCLs) to room temperature remains a key challenge in QCL community. Group-IV semiconductors are believed to be a promising solu...
Electric field-induced bending by polarized surface layers effect in ferroelectric ceramics
Electric field-induced bending in ferroelectric ceramics has attracted considerable interest recently, but the mechanisms of this phenomenon are not fully understood. In this work, we show that electr...
