Schematic diagram showing the mechanism of electric field sensing in the graphene sensors for (a) positive and (b) negative electric fields. In the case of the positive electric field, the electrons are attracted towards the graphene channel from the SiO2 layer. In contrast, electrons are transferred from the graphene channel to the traps in the SiO2 layer for the negative electric field.
