Luminescence of porous silicon and porous silicon encapsulated structures

Monastyrskii Lubomir S., Olenych Igor B., Parandii Peter P.

Abstract

Spectroscopic properties of encapsulated porous silicon (PS) have been studied in detail. In order to investigate different heterostructures of porous silicon a complex of analysis methods such as photoluminescence (PL) electroluminescence (EL), cathodoluminescence (CL) and thermostimulated depolarisation (TSD) were applied. The process of light emission shows a tendency to decrease. This decrease varies for different kinds of luminescence. The EL intensity dynamics depends on polarization effects in porous silicon.
