Abstract

Cathodoluminescence of porous silicon after mechanical damage with a tip has been studied in the scanning electron microscope. Mechanical damage results in the exposure of new surfaces related to fracture and to small particles appearing over the porous silicon layer. The freshly generated surfaces caused an increase of several orders of magnitude in the luminescence efficiency.
