The CdS/CNT composite is of particular interest in many application fields, since it was shown that it is capable of generating photocurrent from visible light with unusually high efficiency and for microwave reduction properties. But there is a little information about the electronic properties. In this paper we focus on improving electrical properties by deposition CdS nanoparticles on CNTs. The...
Algorithm allowing to study the atomic structure and electronic structure of nanoemitters based on carbon nan-otubes (CNT) was developed by quantum approach for the first time. This algorithm takes into account the heterogeneity of the electric field. It was established that the distribution of the electrostatic field intensity varies greatly with the advent of the atoms of the plasma in the area...
Carbon nanotubes (CNTs) are molecular-scale tubes of graphitic carbon with outstanding properties. They are among the stiffest and strongest fibers known, and have remarkable electronic properties and many other unique characteristics. In our experiment, CNTs were synthesized using plasma enhanced chemical vapor deposition on the silicon wafer with patterned iron catalytic layer. If the catalyst is...
A co-planar single walled carbon nanotube (SWCNT) electrode system with all electrodes (working, counter and reference) was fully microfabricated on a glass substrate. The process is based on: (a) a standard microfabrication process to define the conducting tracks and a nitride passivation, (b) a transfer printing of SWCNT film, and (c) a chlorination process of thin-film Ag to form AgCl reference...
We have grown functionalized CNT using the resist-assisted patterning process. The single have enhanced and very stabilized electron emission. We obtained the long term stability which the field emission current of the single emitters remains stable up to 20 hrs. The single emitters can be used in the vacuum nano-electronics devices. More detail electron emission properties should be delivered in...
In this work, a directed assembly technique for controlled micro-patterning of single-walled carbon nanotubes (SWNTs) on to a flexible parylene-C substrate has been demonstrated. A simple site-selective fluidic assembly of SWNTs has been utilized to directly assemble SWNTs on a plasma treated parylene-C substrate to form ordered high density carbon nanotube networks. Continuous nanotube micro-arrays...
Novel dual-scaled superhydrophobic nano-flower surfaces were fabricated by 1-mask photolithography, DRIE and carbon nanotube (CNT) microwave plasma enhanced CVD (MPCVD). Patterned structure was characterized by SEM, TEM and AFM techniques. With the additional petal-like CNT structure, the apparent contact angle (ACA) increased dramatically compared with silicon (~140%) and parylene-coated (~78%) micropillar...
We discuss the use of electron-shading effect during the plasma-enhanced chemical vapor deposition to control the growth of carbon nanotubes (CNTs). We designed and fabricated the trench and island test structures. The horizontally aligned CNTs were grown from the sidewall of the polysilicon structure, parallel to the silicon oxide surface. We investigated the electrical property of the CNT number...
The encapsulation of alkali-metal or halogen inside single-walled carbon nanotubes (SWNTs) can be realized by a novel alkali-halogen plasma irradiation method. According to electronic transport measurements, it is found that a p-type semiconductor behavior can be strongly improved by encapsulating iodine atoms. Furthermore, a p-n junction diode-like feature is observed by selective encapsulation of...
The composite structure of silicon tips and vertical aligned carbon nanotubes (CNTs) was prepared using plasma enhanced hot filament chemical vapor deposition (PE-HFCVD) method on the silicon wafer, and Au/Ni film coated on the substrate was considered as a catalyst. High proportion hydrogen of 96% volume percentage and high total pressure are used during preparing process, and the pure CNTs, pure...
