Non-Fickian current enabling the uphill diffusion of impurities diffusing by the mechanism of mobile impurity-defect pairs
V. I Tokar
Equations governing the diffusion mediated by the mobile pairs have been derived. In addition to known non-Fickian (n-F) behavior observable at small spatiotemporal scale under hom…
Impurity Green's function in the five frequency model of diffusion in the FCC host: General case and the limit of strong impurity-vacancy binding
V. I. Tokar
The impurity Green's function exact to the first order in the vacancy concentration has been calculated in the framework of the five frequency model (5FM). The solution in terms of…
Non-Gaussian diffusion profiles caused by mobile impurity-vacancy pairs in the five frequency model of diffusion
V. I. Tokar
Vacancy-mediated diffusion of impurities under strong impurity-vacancy (I-v) attraction has been studied in the framework of the five-frequency model (5FM) for the FCC host. The sy…
Non-equilibrium gelation transition in a kinetic lattice gas model
V. I. Tokar, H. Dreyssé
We consider a lattice gas model which in addition to the canonical nearest neighbor pair interatomic interaction accounts for a many-body interaction inside atomic trios. Interacti…
Analytical solution of 1D lattice gas model with infinite number of multiatom interactions
V. I. Tokar, H. Dreyssé
We consider a 1D lattice gas model in which the atoms interact via an infinite number of cluster interactions within contiguous atomic chains plus the next nearest neighbor pairwis…
Lattice gas models of coherent strained epitaxy
V. I. Tokar, H. Dreyssé
The harmonic Frenkel-Kontorova model is used to illustrate with an exactly solvable example a general technique of mapping a coherently strained epitaxial system with continuous at…
