For the application of field emission (FE), W18O49 nanostructures have exhibited excellent FE behaviors among tungsten oxides, which promise a much better future. However, many difficulties remain to be overcome in their application in devices. One of them is that synthesis of nanostructures in uniform W18O49 phase is difficult; tungsten oxides have tens of different phases, which can results in their...
Intensive investigation on WO3-x nanostructures has been carried out in the last decade because they possess extraordinary properties. Especially for application in field emission, W18O49 nanostructures have exhibited excellent performance. Some issues have to be addressed in fabricating vacuum microelectronic devices using W18O49 nanostructures, including how to realize well aligned nanostructure...
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...
The authors have developed a new method to fabricate patterned W18O49 nanowire arrays by combination of thermal evaporation and lift-off technology. It is found that the phosphoric acid processing of the lift-off technology has strong effect on the field emission property of W18O49 nanowires.
Summary form only given. Reactive plasmas are commonly known as ideal environments that sustain intense growth of clusters, nano- and even microparticles (also known as "dust"). Recently, it has been shown that such particles under certain conditions can be deposited on solid surfaces during the plasma discharge run. Levitating in the gas phase, these particles can self-organize into voids,...
