Abstract

Electroluminescent nanoporous silicon is investigated by accelerator techniques. Rutherford Backscattering Spectroscopy (RBS) and Nuclear Reaction Analysis (NRA) are used to measure the oxygen content. The stoichiometry is Si1O1.8 in the top layer and Si1O0.8 in 6 μm depth. Channeling experiments show that only very weak channels are present.
