Polymer Thin Film Chemical Sensors

Abstract

FETs, fabricated with single-walled carbon nanotubes, have been found (Collins et al., 2000) to be sensitive to various gases -for example, oxygen, nitrogen dioxide, ammonia, etc. FETs of this type can operate as gas sensors (Qi et al., 2003) on account of their high sensitivity, their fast response time, and their compatibility with dense-array fabrications.www.intechopen.com
