چکیده انگلیسی
ZnO nanorods with different morphologies were grown by changing the temperature of the process using the thermal vapor deposition method without a catalyst. The X-ray diffraction pattern of these nanorods showed a single-crystalline wurtzite structure and a cc-axis orientation. The turn-on fields of the pencil-like and normal ZnO nanorods were 1.7 V/μm and 2.2 V/μm at a current density of 0.1 μA/cm2, and the emission current density from the ZnO nanorods reached 1 mA/cm2 at bias fields of 5.1 V/μm and 7.5 V/μm, respectively. The results indicated that ZnO nanorods could give sufficient brightness as a field emitter in a flat panel display.
