A simple route to annihilate defects in silicon nanowires

... defects after annealing. Raman spectra also con®rmed that the bulk specimen was almost defect-free. By using thermal annealing, defect-free silicon nanowires can be prepared in a simple and practical ... a protective gas and the furnace temperature was increased to 1100°C for 6 h. 1100°C was used as the annealing temperature because nanowires react to become SiO vapor and...
