Phosphorus doping in silicon
WebFor phosphorus-doped silicon, the results of this work differed by 5 % to 15 % from the then commonly used curve. For boron-doped silicon the results differed significantly from the p-type curve in use at the time. A maximum deviation of 45 % occurred at a boron density of 5 1017 cm–3. Because of 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.
