CVD-Grown Graphene Solution-gated Field Effect Transistors for pH Sensing
Published online by Cambridge University Press: 21 March 2011
Abstract
This paper presents the fabrication technology and initial characterization of electrolyte-gated field effect transistor (FET) arrays based on CVD grown graphene on copper. We show that the graphene FET (GFET), when immersed in electrolytes, exhibit a transconductance around 5 mS/mm. From preliminary pH sensing experiments, a pH sensitivity of 24 mV/pH has been demonstrated.
