| 1 | Synthesis of CNT film on the surface of micro-pyramid array and its intense pulsed emission characteristics显示文摘We developed a new scheme to suppress the electric-field-screening effect in high growth density of a carbon nanotube(CNT) film during its intense pulsed emission.We synthesize the CNT film on a tridimensional surface(t-CNT film).The tridimensional surface includes wet etched silicon pyramids,and the Ni layer is electroless plated thereon.The intense pulsed emission characteristics of the t-CNT and planar-grown CNT(p-CNT) films were measured using a diode structure in single-pulse mode.The even turn-on field decreased from 5.5 V/μm for p-CNTs to 2.8 V/m for t-CNTs,and the peak emission current increased from 232 A for p-CNTs to 324 A for t-CNTs at a peak field intensity ~12.2 V/m.The peak current of the t-CNT film increased by ~39.7% over the p-CNT film.It is clear that the micro-pyramid array can effectively suppress the field screening effect to improve the electron-emission of CNT films. | ZENG FanGuang LI Xin LIU WeiHua QIAO ShuZhen MA HuaLi ZHANG Rui XIA LianSheng CHEN Yi LIU XingGuang ZHANG Huang | 2012 | Chinese Science Bulletin2012，57，14： | 10 |
| 2 | Improvement in the intense pulsed emission stability of grown CNT films via an electroless plated Ni layer显示文摘Carbon nanotube(CNT)films were grown on silicon wafers with and without a nickel layer(Si-CNT and Ni-CNT)via the pyrolysis of iron phthalocyanine.The nickel layer was prepared using the electroless plating method.To study the emission stability of Si-CNT and Ni-CNT cathodes during intense pulsed emission,emission characteristics were measured repeatedly with a diode structure using a Marx generator as a voltage source.For the peak values of the pulsed voltage,which were in the range between 1.62-1.66 MV(corresponding to electric field intensities between 11.57-11.85 V/μm),the first cycle emission current was 109.4 A for Si-CNT and 180.5 A for Ni-CNT.By comparing the normalized emission currents of the Si-CNT and Ni-CNT cathodes,the improvement in the emission stability can be easily quantified.The number of emission cycles necessary for the peak current to decay from 100%to 50%increased from^3 for Si-CNT to^11 for a Ni-CNT film. | ZENG FanGuang LI Xin LIU WeiHua QIAO ShuZhen MA HuaLi ZHANG Rui XIA LianSheng CHEN Yi LIU XingGuang ZHANG Huang | 2011 | Chinese Science Bulletin2011，56，22： | 7 |
