• SWNT FETs, for which the mechanisms may be different, is not available. On the other hand, polyethyleneimine (PEI) functionalization for NO2 sensing has been shown to dramatically enhance the response of SWNT sensors [14]. There, the authors argue that the main mechanism of sensitivity enhancement is
