In microporous silicon (microPS) every tenth atom is a surface atom and surface processes in silicon are notoriously difficult to study, making the investigation of effects such as electroluminescence difficult. Add to this the profound effects of varying the production parameters and one has a complicated situation where results are often difficult to interpret correctly. Several preparation techniques are reviewed and recent progress made in understanding microPS discussed.
