|Title: ||Gas sensor based on single wall carbon nanotubes|
|Authors: ||Di Carlo, Aldo|
|Issue Date: ||1-Sep-2008 |
|Abstract: ||Single-walled carbon nanotubes (SWNTs) are nowadays one of the most investigated materials and the realization of
ordered SWNT structures is of fundamental importance for the improvement of many technological fields, from the
non-linear optics to the realization of transistor, to the assembly of gas sensing devices.
A SWNT is formed by rolling a graphene sheet into a seamless cylinder with a diameter on the nanometer scale. The
individual SWNTs are joined each other and assembled into bundles by Van der Waals forces. Guest molecules can
potentially interact with SWNTs via the outer surfaces of bundles, the inside of the tubes and /or the interstitial channels
between the tubes in a bundle. These different situations are expected to play an important role in tuning the guest
molecule/SWNT interaction during gas adsorption and/or desorption, and have been investigated theoretically and
experimentally using different approaches.
In particular, the interaction between gaseous mole...|
