Hydrogen and the Light-Induced Bias Instability Mechanism in Amorphous Oxide Semiconductors.
Hydrogen is known to be present as an impurity in amorphous oxide semiconductors at the 0.1% level. Using amorphous ZnO as a simplified model system, we show that the hydrogens pair up at oxygen vacancies in the amorphous...
Termination-dependence of Fermi level pinning at rare-earth arsenide/GaAs interfaces
ABSTRACT
The properties of metal/semiconductor interfaces are generally described by the metal-induced gap states (MIGS) model. However, rare-earth (RE) arsenide interfaces are found not to follow the MIGS model in having very...
Extending the metal-induced gap state model of Schottky barriers
Fermi level pinning at Schottky barriers strongly limits the minimization of contact resistances in devices and thereby limits the scaling of
modern Si electronic devices, so it is useful to understand the full range of...
Modelling the enthalpy change and transition temperature dependence of the metal-insulator transition in pure and doped vanadium dioxide.
We compare various calculation methods to determine the electronic structures and energy differences of the phases of VO2. We show that density functional methods in the form of GGA+U are able to describe the enthalpy difference...

Ab Initio Study of Hexagonal Boron Nitride as the Tunnel Barrier in Magnetic Tunnel Junctions.
Two-dimensional hexagonal boron nitride (h-BN) is studied as a tunnel barrier in magnetic tunnel junctions (MTJs) as a possible alternative to MgO. The tunnel magnetoresistance (TMR) of such MTJs is calculated as a function of...
Face Dependence of Schottky Barriers Heights of Silicides and Germanides on Si and Ge.
Density functional supercell calculations of the Schottky barrier heights (SBH) of metal germanides and silicides on Si or Ge find that these vary with the facet, unlike those of elemental metals. In addition, silicides and...
Machine‐learning‐based interatomic potentials for advanced manufacturing
Abstract: This paper summarizes the progress of machine‐learning‐based interatomic potentials and their applications in advanced manufacturing. Interatomic potential is essential for classical molecular dynamics. The...
A durable and pH-universal self-standing MoC-Mo2C heterojunction electrode for efficient hydrogen evolution reaction.
Wei Liu, Xiting Wang, Fan Wang, Kaifa Du, Zhaofu Zhang, Yuzheng Guo, Huayi Yin, Dihua Wang

Abstract: Sodium-ion batteries (SIBs) are promising power sources due to the low cost and abundance of battery-grade sodium resources, while practical SIBs suffer from intrinsically sluggish diffusion kinetics and severe volume...
The Association Between Food Addiction and Weight Status in School-Age Children and Adolescents.
BACKGROUND: The association between food addiction (FA) and weight status in children and adolescents remains poorly understood. This study aimed to elucidate the association between FA and weight status using the validated...
