Table 1 Comparison of the field emission properties between the different ZnO nanostructures
From: Synthesis and field emission properties of different ZnO nanostructure arrays
Type of ZnO nanostructure | Turn-on field (V μm-1) | Threshold field (V μm-1) | β |
|---|---|---|---|
Leaf-like (30 min) | 2.94 | 4.35 | 2,800 |
Long NWs arrays (60 min) | 3.69 | 5.72 | 2,526 |
Needle-like | 3.87 | 5.65 | 2,284 |
