This paper presents photoelectrochemical properties of multi-walled carbon nanotube assembled with CdSe quantum dots. CdSe QDs are adsorbed on the surface of MWCNTs with a diameter of 4-5 nm.
In this paper, fabrication and characterization of QDSSCs based on CNT doped TiO2 mesopores film were reported. The improved efficiency is obtained for the device using CNT/TiO2/CdSe as the photoanode. The QDSSCs based on bare TiO2 and CNT doped TiO2 were named as sample A and B.
In this work, bamboo-shaped CNTs were successfully fabricated by PECVD using ZnO:Co thin film as catalyst. ZnO:Co nanoclusters were produced by a nanocluster-beam deposition system. Briefly, a metal target consisting of 98% Zn and 2% Co was used with a sputtering power of 130 W. Ar, He and Oxygen gases were injected into the system with the corresponding total pressure of 0.75 Torr. A plasma enhanced...
Field emission characteristic and stability of a carbon nanotubes (CNTs) cathode have been studied by testing the emission current at different levels. By monitoring the emission I-V curves, we can obtain a relative stable maximum current from a CNTs cathode, after reaching the maximum current, the emission current fluctuate seriously and sparking can be seen at the site of emission. From the experimental...
Double cathodes field emission display is proposed and the structural and electrical parameters are optimized in this paper. The calculation and experimental results shows that this structure can achieve good uniformity and high luminance
