Phosphorus doping in silicon
WebJul 12, 2024 · An alcohol bearing alkyne was thermally grafted to both p-type and n-type silicon (111) and (100) substrate of comparable doping levels and surface flatness. The surface topography as well as the surface chemistry was examined via atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS) and water contact angle … 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.
