Polycrystalline Graphene Ribbons as Chemiresistors
Advanced Materials
(2012)
Abstract
Polycrystalline graphene sensors easily obtained through chemical vapor deposition (CVD) have been developed for chemical sensing. We show that linear defects or continuous lines of point defects on these sensors result in significantly higher sensitivity than that of pristine graphene and carbon nanotube film sensors. Further sensitivity enhancement is obtained by cutting the graphene into ribbons of width comparable to the linear defect dimensions (micrometers).
