Abstract
Zinc oxides nanowires (ZnO NWs) were successfully synthesized on bare silicon substrates using Chemical vapour deposition (CVD) method without foreign catalyst. The ZnO NWs had good crystal quality as they exhibited a strong UV emission (373 nm) corresponding to the free exciton emission and a weak green arising from defect-related emission in PL measurement. Measurement of low temperature photoluminescence spectra show a peak of free exciton and defect bound excitons. The growth of these catalyst-free ZnO NWs was governed by Vapour-Solid (VS) mechanism.
