Tetrapod-like ZnO nanostructures serving as cold cathodes for flat panel displays
四角状氧化锌纳米材料的场致发射平板显示器

We have studied the field emission properties of tetrapod-like ZnO nanostructures and the fabrication of flat panel displays. Stable field emission and full-screen lighting have been realized. It is shown by our experimental results that ZnO nanometerials are good field-emission cathode materials.
