In this work, we propose a simple method to form uniform carbon nanotube network (CNTN) in wafer-scale, which is completely compatible to thin-film transistors (TFTs) process and can achieve large-area uniformity and stable device performance. From the plot of on-current versus off-current, it is clear that devices with various dimensions are divided into two groups, and the threshold value for these...
In this work, carbon nanotube based electrochemical sensor array was developed as electronic tongue for beer discrimination without sample pretreatment using chronoamperometry. To form the sensor array, carbon nanotubes were modified by oxygen plasma and electrochemical oxidation using NaOH and KClO3 to yield electrochemical sensors with distinct characteristics. The current sensitivities from differently...
In this study, a simple process has been proposed for vertically aligned CNT growth on metal foil and then the applied CNT emitter as electron source for X-ray generation.The CNTs were grown using a triode dc-PECVD (plasma enhanced chemical vapor deposition). The growth temperature was maintained at 700 degC. To confirm the electron emission of the vertically aligned CNTs on metal foil, emission current...
Numerous studies have been conducted to date on field emission from carbon nanotubes (CNTs). For CNT film, there were two main methods: direct growth of CNTs onto a substrate, post-treatment to make CNTs adhered onto substrate. In this work, the adhesive taping method was adopted to improve the stability and reproducibility.
In recent years, there has been increasing interest in monitoring and controlling of pH. It has become an important aspect of many industrial wastewater treatment processes. At the same time, the demand for smaller electronic devices used for various industrial and commercial applications has greatly increased. Micro and nano materials, such as Carbon Nanotubes (CNTs) are known for their excellent...
