Research output: Contribution to journalArticlepeer-review


Electromigration in a two-phase structure is considered and analyzed. Concentration gradient is not a driving force of diffusion in this case and does not oppose the segregation. The microstructure instability is due to the lack of chemical-potential gradient to counteract the electric field. No steady state of composition gradient will take place. Instead, random local states of phase separation precede a complete phase separation. Kinetic analysis of flux migration in two-phase structure under the constraint of constant volume is given.
