a simple method to synthesize nanowires titanium dioxide from layered titanate particles

A simple route to annihilate defects in silicon nanowires

... used asthe annealing temperature because nanowires react to become SiO vapor and disappear above thistemperature [21]. During annealing, a total pres-sure of 740 Torr was maintained. Afterwards,small ... defects after annealing.Raman spectra also con®rmed that the bulk specimen was almost defect-free. By using thermal annealing, defect-freesilicon nanowires can be prepared in a simple and practical ... However, these nanowires containedmetallic nanoparticles, since gold was added as a catalyst in this method. This metallic contamina-tion will degrade the properties of the nanowires. As we reported...
