Description
Summary:Single-walled carbon nanotubes (SWNTs) have a unique quasi-1D electronic structure which displays remarkable versatility and promises wide applicability. Among their many potential applications, field-effect transistors(FETs), fabricated with SWNTs, have been found to be sensitive to various gases–for example, oxygen, nitrogen dioxide, ammonia, etc.–and so FETs of this type can operate as gas sensors on account of (i) their high sensitivity, (ii)their fast response time, and (iii) their compatibility with dense-array fabrications.
