    Abstract

    This paper presents a stimulus-response method for surface potential sensing of silicon nanowire field-effect transistors (Si-NW FETs). When an ‘ion-step’ from low to high ionic strength is given as stimulus to the surface, a change of current through the Si-NWs is measured. When the surface potential is changed from negative for a bare SiO2 surface to neutral/positive when there is poly-L-lysine adsorption, this change is measured by a change in current variation at the ion-step.
