Abstract

We show that the optical absorption and emission energies in porous silicon can be accounted for in a quantum wire confinement model where both the electron and the hole are localized by lateral surface wire undulations. Localization energies for both the particles have been numerically calculated within the effective mass approximation showing that there exists a limited class of wire geometries which are consistent with porous silicon optical and structure analysis data.
