摘要：

The zinc oxide (ZnO) nanowires with different morphology and diameter were synthesized on silicon (100) substrates by heating pure zinc powder at low temperatures of 450 degrees C and 480 degrees C. Scanning electron microscopy (SEM) was used to analyze the morphology and diameter of samples. The electron field emission properties between different morphology of ZnO nanowires samples were compared. A low turn-on field at 3.6 V/mu m was observed from nanorods due to better alignment, and a strong emission current density of 3.6 mA/cm(2) at electronic field 9.0V/mu m was obtained from needle-like nanowires sample. The emission stability of ZnO samples is also presented. (c) 2005 Elsevier B.V. All rights reserved.
