We developed deep UV generation techniques with home-made wide bandgap anode and carbon nanotube (CNT) based cold cathode electron beam (C-beam). The wide bandgap anodes excited with high performance C-beam. The fabrication process for anodes were developed and optimized for high performance deep UV generation. Also, the performance of C-beams optimized. With the optimized C-beam and anode, we could...
The principle of field-emission display is almost the same as the traditional cathode ray tube, so it should display the image with the same quality as CRT. However, the triode structure and uniformity of field-emission is two key issues regarding the field-emission display. In this paper, a planar triode is discussed deeply. The structure of this planar triode is quite simple, and it can be fabricated...
Study has been carried out into the key technological issues related to the fabrication of 4.3-inch CNT field emission flat panel light source. Controlled growth and post treatments are found to be effective approaches for achieving uniform luminescence of the light source.
Using the insulation slurry as materials, the anode hiding layer was fabricated on the anode glass faceplate with the screen-printing process for improving the display image performance. The insulation wall including several rectangular insulation blocks was developed used to sustain the glass faceplate. The gap would exist between the different insulation blocks because the insulation blocks were...
We report here an effective method for the fabrication of a large number of carbon nanotube (CNT) triode-type micro-cathodes. Our technique combines composite electroplating and micromachining, avoiding the tedious direct growth and the screen-printing procedures conventionally used to fabricate such structures. The emitter structure is characterized by uniform diameters and heights, as well as by...
In this paper, we fabricated organic-free thin multi-walled CNT (thin-MWCNT) field emitters using a new filtration-transfer method. The method firstly forms the density-controlled thin-MWCNT film on a filter membrane by filtration and then transfers the film to a conductive adhesive tape. We evaluated and compared the genuine field emission properties of various CNT field emitters by using the filtration-transfer...
This presentation deals on the preparation and field-emission behaviour of CNT-based cold cathodes to be used in space-related applications and for fabrication of miniaturized X-ray tubes (NANORAY project, FP7-SME-2007).
We present a fabrication technique for the integration of a gate electrode with an array of carbon nanotube (CNT) emitters. These gated cathode structures have high emission current density and may be utilized in X-ray tubes, traveling wave tubes, and ion propulsion systems. The CNT emitters are grown directly on polished bulk metal substrates and are comprised of CNT bundles that are vertically aligned...
In this paper we outline a process for the integration of gated CPAs. The process employed to fabricate this gated cathode is highly scaleable and promises the realization of stable high current cold cathodes with low turn-on voltages for many potential applications. In addition, we will present data detailing the field emission performance and reliability of gated carbon nanotube pillar arrays.
A design study of a 0.1-THz coupled-cavity backward-wave oscillator (CCBWO) is presented using a finite element method and a particle-in-cell simulation. In experiments, the Si-based technology of 2-step deep reactive ion etching (DRIE) and eutectic bonding shows a good potential for the microfabrication of the interaction circuit. A miniaturized field emission cathode using carbon nanotubes grown...
We demonstrate a fully integrated, on-chip, vacuum microtriode capable of handling voltages up to 800 V. The ability to operate at such high voltages is achieved by the addition of a 10 mum-thick silicon dioxide layer to the device. The device is fabricated using MEMS fabrication principles and utilizes carbon nanotubes as field emitters. A dc amplification factor of 600 was obtained. To the best...
