Silicon Structures

Two-dimensional silicon structures are currently attracting a great deal of attention due to their potential application in the electronic and energy sectors. Most published works have employed simple face-centered cubic (fcc) models in determining dispersion curves and density of states for silicon. In this paper we address confinement effects in silicon using a two- and three-body environment-dependent interatomic potential (EDIP). Dispersion curves for silicon thin films under free-standing boundary conditions are theoretically computed by means of the dynamical equation. We show how size confinement causes the emergence of new energy levels and a flattening of the dispersion curves, explaining the reduction of phonon group velocities with respect to bulk, and the change in the volumetric specific heat. Our results indicate when confinement effects begin to play a primary role in the dynamical behavior of the structure and allow the prediction of the number of atomic layers above which a silicon film can be considered thick in terms of its dynamical behavior.

Fluid Theory

The micropolar fluid theory, a possible non-Newtonian model for fluids with rigid particle additives in which the average molecular size may be comparable to the material characteristic length, is applied to a two-dimensional problem of squeeze film of a ball in a spherical seat and to some three-dimensional noncyclic squeeze film problems, assuming the characteristic coefficients to be constant, in an effort to study the effects of rigid particle additives for the three-dimensional micropolarity model. Increase in effective viscosity due to the presence of additives is established theoretically. It is also shown that the theoretical effects of the additives on three-dimensional lubrication are identical to the two-dimensional problems, at least qualitatively.
