Applied Physics A: Materials Science & Processing, 2003
Transient effects on diffusion and activation during post-implantation anneals are a major obstacle for the further miniaturization of ultra-large-scale integrated semiconductor devices. The article reviews recent developments in the simulation of such phenomena with particular emphasis on models for the kinetics of self-interstitial agglomerates and ...

Preferential diffusion effects in diffusion flames
2008Numerical computations were made of axisymmetric laminar jet diffusion flames taking into account detailed chemical kinetics and multicomponent diffusion. It was shown that preferential diffusion of heat and species causes significant amount of excess and deficit of enthalpy, and increase and decrease of mole fraction in the flame. These effects result

Applicability of transfer entropy for the calculation of effective diffusivity in heat transport
Physics of Plasmas, 2018A method has been proposed to study heat transport in magnetically confinement plasmas, based on the transfer entropy (TE). In this work, we study this method by introducing perturbations in simulations made using a resistive Magneto-HydroDynamic model ...

Effective diffusivity in transient state
The Journal of Chemical Physics, 2013The effective diffusivity in a polymer matrix modified with inclusions is usually calculated based on Kalnin-Kotomin's model [J. R. Kalnin, E. A. Kotomin, and J. Maier, J. Phys. Chem. Solids 63, 449–456 (2002)]10.1016/S0022-3697(01)00159-7, which extends the well known Maxwell-Garnett formula.

Ternary diffusion and effective diffusion coefficients in alveolar spaces
Respiration Physiology, 1980An experimentally verified mathematical model of non-equimolar ternary gas diffusion is applied to simulate the conditions existing in the alveolar spaces. When a fictitious gas film is erected a certain distance away from the alveolar membrane, and when the compositions at the two boundaries of the film are, respectively, the alveolar gas composition ...

Baro-Diffusion Effect on Diffusion Time
The Physics of Fluids, 1967The evolution of the concentration distribution of a small quantity of a heavy gas diffusing in the steady flow field of a lighter gas is investigated. Two cases are treated: (1) the lighter parent gas is initially in rigid body rotation, (2) it is initially at rest under a strong body force.

Effective Diffusion Coefficient
Defect and Diffusion Forum, 2018The diffusion of a B element into an A matrix was studied by the random walk theory. Considering that concentration of B element in the A matrix is very low, the jumps of diffusing atoms are independent of each other. The A matrix is a two-region material with different properties, such as a two-phase material, a single crystal with dislocations, or ...
