Abstract
The structure of porous silicon (PS) was simulated by a two-dimensional site-percolated network model. In this model, both porosity and geometrical morphology were independently controlled. The conductivity of the generated PS structures were numerically simulated, and the effects of porosity and geometrical connection of PS on the conduction behavior of percolated Si network were isolated and identified. It was shown that the geometrical connection of PS causes its conduction behavior to become distinctly different from that in a random network. © 1997 Elsevier Science S.A.
