Electromigration and the structure of metallic nanocontacts

R Hoffmann-Vogel - Applied Physics Reviews, 2017 - pubs.aip.org
This article reviews efforts to structurally characterize metallic nanocontacts. While the
electronic characterization of such junctions is relatively straight forward, usually it is …

[HTML][HTML] Two dimensional phase field crystal study of thermo-density coupling: Thermal expansion, recalescence, and plasticity

D Burns, N Provatas, M Grant - Acta Materialia, 2024 - Elsevier

Generalizing the structural phase field crystal approach for modeling solid-liquid-vapor phase transformations in pure materials

DL Coelho, D Burns, E Wilson, N Provatas - Physical Review Materials, 2024 - APS
In a recent class of phase field crystal (PFC) models, the density order parameter is coupled
to powers of its mean field. This effectively introduces a phenomenology of higher-order …

Closing the gap between atomic-scale lattice deformations and continuum elasticity

M Salvalaglio, A Voigt, KR Elder - npj Computational Materials, 2019 - nature.com
Crystal lattice deformations can be described microscopically by explicitly accounting for the
position of atoms or macroscopically by continuum elasticity. In this work, we report on the …

Electromigration-induced surface drift and slit propagation in polycrystalline interconnects: insights from phase-field simulations

A Mukherjee, K Ankit, M Selzer, B Nestler - Physical Review Applied, 2018 - APS
We employ the phase-field method to assess electromigration (EM) damage in wide
polycrystalline interconnects due to grain-boundary grooving. An interplay of surface and …

Step bunching with both directions of the current: Vicinal W (110) surfaces versus atomistic-scale model

O Toktarbaiuly, V Usov, C Ó Coileáin, K Siewierska… - Physical Review B, 2018 - APS
We report the observation of bunching of monoatomic steps on vicinal W (110) surfaces
induced by step-up or step-down currents across the steps. Measurements reveal that the …
