On-chip assembly of 3D graphene-based aerogels for chemiresistive gas sensing

Abstract

Integration of the material preparation step into the device fabrication process is of prime importance for the development of high performance devices. This study presents an innovative strategy for the in situ assembly of graphene-based aerogels on a chip by polymerization-reduction and annealing processes, which are applied as chemiresistive gas sensors for the detection of NO2.
