Physics‐Guided Modeling of Temperature‐Dependent Electrical Conductivity of Functional Oxides

Advanced Intelligent Discovery, EarlyView.
This complete workflow presents an automated, data‐driven screening of functional oxides based on their predicted electrical conductivity. A curated dataset is fed into TriCondNet, a charge‐transport, physics‐guided neural network that classifies an input composition's conduction mechanism and then simulates its conductivity–temperature profile.

Temperature dependence of lattice parameter, misfit and thermal expansion coefficient of matrix, gamma phase and superalloy

, 2001
In order to determine the temperature dependence of the misfit of the nickel based superalloy CMSX 4, the lattice parameters of its constituents, amp; 947; amp; 8242; phase and a nickel solid solution, have been determined by neutron diffraction ...

On the Impact of Mechanical Constraint on Band Structure and Photo‐Elastic Effect in Photonic Resonators

Advanced Physics Research, EarlyView.
We computationally investigate the mechanical, electronic, and optical properties of strained GeSn microdisks on silicon substrates. By combining photo‐elasticity, strain‐dependent band‐structure calculations, and optical mode analysis, we study how strain distribution, structural configuration, and temperature affect the electronic band structure and ...

Diffusion‐Governed Growth Mechanisms of Epitaxial GaAs Islands on CMOS‐Compatible Si(001) Nanotip Arrays

Advanced Physics Research, EarlyView.
The mechanism and kinetics of selective GaAs growth on Si nanotip wafers via nanoheteroepitaxy were investigated as a function of pitch (center‐to‐center nanotip spacing). The pitch dependence reveals distinct surface‐diffusion‐controlled regimes, demonstrating that lateral Ga adatom transport on the SiO2 mask governs material redistribution and ...

Elemental partitioning, lattice misfit and creep behaviour of Cr containing γ′ strengthened Co base superalloys

, 2016
Novel Cr containing Co-Al-W base superalloys were studied by atom probe tomography and neutron diffraction. Cr is found to predominantly partition to the gamma matrix decrease partitioning of W to gamma'.

One-dimensional photonic crystal with realistic interfaces: Effects of misfit strain

, 2009
International audienceThe influence of misfit strain on the transmission spectra of a photonic crystal, as induced by the difference in lattice parameter of its constituents, is theoretically and numerically ...

Effect of in-plane strain anisotropy on (011) epitaxial BaTiO3 and PbTiO3 thin films

AIP Advances, 2017
Misfit strain phase diagrams of single-domain (011) epitaxial BaTiO3 and PbTiO3 thin films are computed using a thermodynamic phenomenological approach. In the case of (001) epitaxial films, the two orthogonal in-plane misfit strains are equivalent. For (

Lattice misfit versus performance of thin film electroluminescent structures

Journal of Applied Physics, 2001
Thin polycrystalline electroluminescent thin films (TFEL) of ZnS:Mn (phosphor) and Y2O3 (insulator) were deposited individually or as multilayers onto Si (100) substrates. Their crystallinity and the luminescent efficiency of the phosphor films were investigated at varying thermal annealing temperatures.
