Percolation is a concept widely used in many fields of research and refers to the propagation of substances through porous media (e.g., coffee filtering), or the behaviour of complex networks (e.g., spreading of diseases). Percolation theory asserts that most percolative processes are universal, that is, the emergent powerlaws only depend on the general, statistical features of the macroscopic ...

Self-affine elastic contacts: percolation and leakage.

We study fluid flow at the interfaces between elastic solids with randomly rough, self-affine surfaces. We show by numerical simulation that elastic deformation lowers the relative contact area at which contact patches percolate in comparison to traditional approaches to seals. Elastic deformation also suppresses leakage through contacts even far away from the percolation threshold. Reliable es...

A ug 2 00 1 Concentration Gradient , Diffusion , and Flow Through Open Porous Medium Near Percolation Threshold via Computer Simulations

The interacting lattice gas model is used to simulate fluid flow through an open percolating porous medium with the fluid entering at the source-end and leaving from the opposite end. The shape of the steady-state concentration profile and therefore the gradient field depends on the porosity (p). The root mean square (rms) displacements of fluid and its constituents (tracers) show a drift power...

Statistical simulations of oxide leakage current in MOS transistors and Floating Gate memories

The purpose of this paper is to illustrate a physicallybased model allowing the statistical simulations of oxide leakage currents in MOS transistors and Floating Gate memories. This model computes the leakage current through defects randomly generated in the oxide, in case accounting for the formation of percolation paths. Furthermore, a calculation procedure has been developed to calculate the...
