WebP-doped Si nanocrystals (radius <=2 nm) were synthesized by depositing an ultrathin (0.3 nm) P- SiOfilm close to each SiO layer of SiO/SiOmultilayers. During annealing P atoms migrate into the Si-rich region. Due to the low diffusivity of P in SiO, P atoms segregate in the Si nanocrystal region and are incorporated in the silicon nanostructures. WebPure silicon is a very poor conductor of electricity. However, it is industrially viable for semiconductors when it contains a small amount of impurities (such as phosphorus). The introduction of these impurities is called doping. At the research neutron source, doping is achieved using neutrons.
