Carbon nanotubes (CNTs) on a glass substrate at a dramatic low temperature was obtained by a radio frequency plasma enhanced thermal chemical vapor deposition. Nickel film was heated and activated at 450 °C with 2400W rf plasma power, the deposition of the CNTs was performed for 60 minutes with 600W, 1500W and 2400W rf plasma power. The diameters of the CNTs obtained are from 8 to 40 nm and the lengths are about over 1.0 um. SEM micrographs show the lower synthesis plasma power can do better for the CNTs synthesis than the exorbitant rf plasma, the Raman spectra and Field emission properties proved this result. The field emission of the film shows the turn-on emission threshold field is 1.17V/um at an emission current density of 1 uA/cm. At this temperature, the glass did not exhibit deformation; electron emission sufficient for flat panel displays is an important progress in the integrated progress of glass sealed field emission displays.

As we know, the unsatisfactory field emission from the films by electrophoresis is resulted from the weak adhesion. The main aim of this paper is to improve the adhesion surrounding electrophoresis technologies. In addition, A simple controllable method is reported for the coating of ZnO nanowires with Ag nanoparticles and ZnO/Carbon nanotubes (CNT) composite.

In this paper, the low-cost screen printed method was adopted preparation uniform nano-SiC films on large areas of glass. The reunited nano-SiC was dispersed by ultrasonic before fabricating paste. After fabricating paste, the nano-SiC was further ultrasonic dispersed. The nano-SiC paste was screen printed on glass. Then nano-SiC films was sintered by the furnace controlled artificial intelligence, the anneal test was take to improve the field emission characteristics. The samples of nano-SiC film were micro-analyzed and tested the I-V characteristics. After above experiments and technics, the uniformity and stability of field emission characteristics for nano-SiC film was obtained.

As we know, the unsatisfactory field emission from the films by electrophoresis is resulted from the weak adhesion. The main aim of this paper is to improve the adhesion surrounding electrophoresis technologies. The technique we applied is referred to employ both organic binders and inorganic solution simultaneously. In addition, the influences of the applied voltage, inter-electrode distance and deposition time on the compound coatings were specifically investigated. The results of the experiments indicated that field emission current of the electrophoresis deposition film were remarkably enhanced compared with the traditional electrophoresis technology.

The new composites of carbon nanotube with silicon dioxide (SiO/sub 2/) nanoparticle for FED cathode is studied. It has significantly improved emission current density property and stable emission characterization of cathode, because it has higher enhancement factor and less shield-effect by adjusting silicon nanoparticle content. The results indicated that when about 80 wt% CNT is optimum content, the current density at the electric field 2 V//spl mu/m is 56 mA/mm/sup 2/, the turn-on field of the CNTs cathode was about 0.71 V//spl mu/m. The fluctuation of emission current is less than 3% for three hours.

The field emission current as a function of the closed-end single-walled CNTs was investigated by using the tight-binding approximation including curvature effect. The discontinuous field emission electron energy distribution and multi-peaks electron emission were found.

ZnO nanowires with high quality and high yield can be obtained based on the simple thermal evaporation of metal zinc in situ at low temperature, which are repeatable. It's suggested that we can use the ZnO nanowires to develop nano-optoelectronics devices and sensors

amorphous silicon nanowire arrays have been successfully prepared by thermal evaporation under the electric field, the dependence of electric field on the growth of amorphous silicon nanowires is studied with the help of scanning electron microscope (SEM) , energy disperse X-ray spectroscopy (EDX) attached to SEM , transmission electron microscopy (TEM). The results show that silicon nanowires grown along straight line and paralleled to each other are located in the middle of two knots. The formation of Si nanowire arrays is controlled by the charged cluster model. And, we suggested that this method can be applied to synthesize other kinds of nanowire arrays.

An architecture for carbon nanotube field emission display based on screen-printing process is presented in this paper. Both the CNT film of cathode and phosphor layer of anode are prepared by screen-printing process. When the space of between cathode and gate electrode and between anode and gate electrode are 0.1 mm and 2.5 mm respectively, very good control ability of gate electrode can be achieved under below 25 V gate voltage and 750~770 V anode voltage

The effects of NH3 on the growth characteristics of carbon nanotubes (CNTs) were systematically investigated in plasma enhanced chemical vapor deposition (PECVD) with C2H2 as a carbon source. The well aligned CNTs were grown from the Ni nanoparticles by plasma-enhanced chemical vapor deposition (PECVD). CNT films were formed with uniform surface morphology instead of nanotube-features. High-resolution transmission electron microscopy revealed that nanotubes grow from the boot with high adhesive ability. The lowest suitable growth temperature is around 560degC. The threshold field is smaller than 2 v/mum, the current within linear extend is from 200 to 700 mA. The luminescence of the CNTs film is not uniform, which resulted from the reduction of field screening effect

To further disclose the emission mechanism and improve emission characteristics of carbon nanotubes (CNT) array films, some parameters affecting field emission characteristics were studied. The field-enhancement factor on the CNT's tip as a function of the CNT's radius r, height L, along with the inter-tube distance was simulated by self-developed CNTFENS2 software in terms of Laplace equation. The results of numerical simulation indicated that the height and radius of the CNT could affect the field emission of the CNT film. Another finding was that the inter-tube distance thus number density of CNT on the substrate could affect the field-enhancement greatly due to the screening effect of nearby CNT.

Novel dual-intercontrolled photosensitive thyristors based on the lateral interaction effect between two current-controlled negative resistance switches with a metal/insulator (tunnel)/n-p/sup +/ semiconductor (MINP) four-layer structure have been developed. The thyristor consists of two MIS switches. Their electrical and optical characteristics and fabrication process are reported. These devices have been further developed to be optically controlled AND/OR gates. >
