Field emission displays (FEDs) have attracted much attention due to its advantages of high luminance, wide viewing angle, fast response and low power consumption. The structure is one of the key issues for the success of FED. Gate structure is widely used in FED for its outstanding advantages, such as lower driving voltage, higher resolution, controllable focusing and so on. In the present work, the...
Many researchers have reported that ZnO nanowires have good field emission properties which meet the requirement of FED [1, 2]. However, preparation under moderate temperature is essential for FED application because usually glass substrates are used in such devices. Locally growth is also demanded. Thermal oxidation is an approach by which ZnO nanowires can be prepared under relatively low temperature...
Tungsten oxide nanostructures have been paid much attention because of their particular physics and chemical properties. But until now, it is difficult to realize patterned growth of tungsten oxide nanowire arrays. In this paper, we demonstrate that tungsten oxide nanowire arrays can be controllably synthesized in patterned arrays at low temperature of 550°C by a simple ceramic template method. The...
W18O49 nanotip arrays were prepared by a two-step high-temperature, catalyst-free physical evaporation deposition process in high-purity argon gas. The prepared products were characterized by scanning electron microscopy, energy-dispersive spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy and transmission electron microscopy. Field emission measurements were carried out with a transparent...
Field emission display (FED) as one of the next generation display technologies, has attracted the attentions of many researchers. Preparation of low cost cold cathode material for FED application is the topic that attracts much attention in this area. In this paper, the vacuum gap dependence of field emission characteristics of polymethyl methacrylate (PMMA) polymer thin film were observed. The observed...
