abstract = {The transport and noise properties of fabricated,
high-performance,gate-all-around silicon liquid-gated
nanowire field-effect transistor devices areinvestigated in
different concentrations of MgCl2solutions. The
criticalconcentration of MgCl2solution for charge inversion
at the solid-liquidinterface is verified using noise
spectroscopy and confirmed using thecapacitance-voltage
measurement technique. In this study, it is found that
theHooge parameter (𝜶H) and the equivalent input noise
(SU) can effectivelyreflect the ion behavior on the surface
of the nanowire. Moreover, the noisecurves for𝜶Hand
SUindicate two turning points at concentrations of 10−4and
10−1m for a peak and a valley, respectively. The noise
transformation isrelated to the behavior of ions near the
solid-liquid interface in solutions withdifferent
MgCl2concentrations is revealed. The results show that
noisespectroscopy is a powerful method for monitoring charge
dynamic processesin the research field of biosensors.},
