Electron field emission properties of carbon nanotubes during thermal heating and laser irradiationMultiwalled carbon nanotubes on aluminum or indium tin oxide layers were irradiated with gallium focused ion beams ͑FIBs͒ to induce defects and increase emission sites of carbon nanotubes ͑CNTs͒. A turn-on voltage was found to decrease from 460 to 220 V by ion irradiation at a dose of 1 ϫ10 15 /cm 2 , corresponding to turn-on fields from 3.7 to 1.8 V/m. However, noticeable improvements in emission characteristics were not observed as a result of high-dose FIB irradiation at and above 1ϫ10 16 /cm 2 . Because of the local temperature rise due to the intense FIB this irradiation resulted in melting of CNTs. The third harmonic of a neodymium-doped yttrium fluoride ͑Nd:YLF͒ laser light was irradiated over screen-printed CNT cathodes, which resulted in turn-on voltage decreasing from 400 to 320 V, corresponding to turn-on fields from 3.2 to 2.6 V/m, with increased emissions by a factor of 6.
Abstract— We have developed a 470 × 235‐ppi poly‐Si TFT‐LCD with a novel pixel arrangement, called HDDP (horizontally double‐density pixels), for high‐resolution 2‐D and 3‐D autostereoscopic displays. 3‐D image quality is especially high in a lenticular‐lens‐equipped 3‐D mode because both the horizontal and vertical resolutions are high, and because these resolutions are equal. 3‐D and 2‐D images can be displayed simultaneously in the same picture. In addition, 3‐D images can be displayed anywhere and 2‐D characters can be made to appear at different depths with perfect legibility. No switching of 2‐D/3‐D modes is necessary, and the design's thin and uncomplicated structure makes it especially suitable for mobile terminals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
