In the present work, experiments have been carried out to study locally-grown ZnO nanowires on the drain-electrode of MOSFET by low-temperature solution-phase method and the effect of active control on field electron emission.
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...
In the present work, we presented our findings on enhancing field emission of low temperature solution phase grown ZnO NWs by using diamond like carbon (DLC) thin film.
ZnO nanowire films were grown on stainless-steel disc with a thin layer of Au as catalyst by thermal evaporation in a vacuum chamber. Morphology of the nanowires was investigated by scanning electron microscopy, while emission site distribution images were recorded by a CCD camera. The nanowires were then used as cathodes in a luminescent tube and its turn-on and threshold voltages and fields, and...
Summary form only given. Due to the discrete structure of energy levels and an enhanced surface-to-volume ratio, energy relaxation and recombination dynamics in colloidal quantum dots (QDs) are significantly different from those in bulk materials. Energy relaxation leads to a fast establishment of quasi-equilibrium populations of electron and hole quantized states (sub-ps time scale). Depopulation...
