Abstract

The morphology of porous silicon layers has been investigated by polarization resolved photoluminescence measurements in different geometrical arrangements. A uniaxial alignment of the long ellipsoidal axis of the aspheric Si nanocrystallites (NCs) parallel to the [100] growth direction is found. This overall orientation of the NCs is randomized with decreasing size of the NCs.
