Abstract:

Porous silicon exhibits extremely rich morphological features resulted from a set of very complex reaction processes at the silicon/electrolyte interface. Numerous theories have been proposed since its discovery more than four decades ago, but there is still a lack of global understanding of the formation mechanisms with respect to the observed morphological details. This presentation will provide a summary of the morphological characteristics of porous silicon and its historic development, and attempt to provide a conceptual analysis of the various aspects in the formation mechanisms of porous silicon in light of currently available information on the fundamental reaction processes on silicon electrodes.
