Microscopic Estimates for Electromigration Velocities of Intragranular Voids in Aluminum Lines
L. K. Wickham, James P. Sethna
We explore the effect of faceting on possible mechanisms for mass transport around electromigration voids in aluminum interconnects. Motivated by linear response estimates which su…

Disorder-Driven Pretransitional Tweed in Martensitic Transformations
Sivan Kartha, James Krumhansl, James Sethna +1
Defying the conventional wisdom regarding first--order transitions, {\it solid--solid displacive transformations} are often accompanied by pronounced pretransitional phenomena. Gen…

Fast Domain Growth through Density-Dependent Diffusion in a Driven Lattice Gas
L. K. Wickham, J. P. Sethna
We study electromigration in a driven diffusive lattice gas (DDLG) whose continuous Monte Carlo dynamics generate higher particle mobility in areas with lower particle density. At…
