Abstract

Production of highly oriented Carbon Nanotubes (CNTs) array is desirable when enhanced electrical properties are required for better performed nanotubes-based devices. The conventional method produces single array CNTs which does not fulfil the requirement for two terminal devices. The study reports a successful production of double layer structure of aligned carbon nanotubes array as a result of the sandwich growth via thermal Chemical Vapor Deposition (C VD) method. Unlike the reported microwave plasma C VD method which uses a tiny top substrate, the high density aligned multiwalled CNTs grown here are from equal-sized catalyst coated substrates stacked in the sandwich configuration. This proves that thermal CVD method is capable of producing good quality, freestanding CNTs array that are connected to two surfaces for possible application in the two terminals electronic devices.
