Abstract
The surface potential is a crucial characteristic of solid-liquid interfaces that can influence the interfacial arrangement. However, previous research has largely neglected the surface potential impact of substrate effect on sensing performance. This work reports an experimental investigation of suspended/supported oxygen-modified graphene field-effect transistors in different ionic concentrations. According to the results, surface potential markedly influences interfacial characteristics, and this effect becomes more pronounced in solutions with varying ionic concentrations. Simultaneously, low-damage oxygen-modified graphene exhibits higher sensitivity to ionic solutions. This paves the way for low-damage modified graphene to expand its applications in the sensing field.
