Abstract
In this contribution we report on the influence of the electrolyte on transport properties of the silicon nanowire (NW) field effect transistor (FET) biosensor studied using noise spectroscopy. The results show that exposing the Si NW FET top and side surfaces to the electrolyte solution not only affects the threshold voltage, but also influences the charge state of the gate dielectric traps. NWs of different lengths were used to investigate the effect of the electrolyte on channel conductivity.
