Abstract
There are many different techniques for the synthesis of carbon nanotubes (CNTs), and plasma technologies experience a significant competitor in thermal chemical vapor deposition (CVD) processes. A particular process is, therefore, selected according to the specific requirements of an application, which clearly differ for the development of composites as compared to nanoelectronics, field emission, displays, sensors, and the like. This paper discusses the method for the synthesis of CNTs using an atmospheric-pressure microwave (MW) torch. It was successfully applied in the fast deposition of multiwalled nanotubes (MWNTs) on a substrate without the necessity of any vacuum or heating equipment. Dense straight-standing nanotubes were prepared on Si substrates with and also without barrier SiOx layer. Therefore, it was possible to produce CNTs directly on conductive Si and to use them as an electron-emitting electrode of the gas pressure sensor. The CNTs grown in MW torch were also used to create a gas sensor based on the changes of electrical resistance measured between two planar electrodes connected by the CNTs.
Abstract (in Czech)
V článku je uveden krátký souhrn aplikací a metod produkce uhlíkových nanotrubek se zvláštní zřetelem na produkci nanotrubek v mikrovlnném plazmovém hořáku za atmosferického tlaku. Jeho vysokou efektivitou pro růst CNT přímo na Si substrátech s možností selektivního růstu. V závěru je popsáno využití těchto Si/CNT vzorků odporových senzorů plynů.
