主 题:NO2 sensitivity ChemFET sensor self-assembly polyaniline poly (acrylic acid)
摘 要:Based on conventional metal-oxide-semiconductor field-effect transistor (MOSFET),a novel kind of chemical field-effect transistor (ChemFET) gas sensor array has been designed and *** obtained sensor consists of self-assembly polyaniline (PAN) composite film containing poly(acrylic acid) (PAA) which was used as gate material of MOSFET instead of conventional metallic *** UV-Vis absorption spectra of PAN/PAA films were *** NO2gas sensitive property of the ChemFET sensor array was also *** show that the drain current of devices increases with increasing of back-side voltage,and decreases with the increase of NO2concentration when the NO2concentration is below 20μg/*** temperature dependence of ChemFET sensor array shows that the drain current of ChemFET sensor decreases with increasing of temperature.
