Epitaxial Graphene on SiC: A Versatile Sensing Platform for High Sensitivity Applications

Abstract

Epitaxial graphene on silicon carbide has become more available through the increased throughput and reduced price of 4 inch SiC-wafers lately. Particularly if used as a transducer and not directly as the sensing material, the graphene surface can be modified to tailor the sensing properties to the desired application. Herein we show that the low-noise and highly sensitive transduction renders epitaxial graphene on SiC a suitable platform for a range of environmental monitoring applications requiring tracelevel detection.
