abstract = {High-quality liquid gate-all-around (LGAA) silicon nanowire
(NW) field-effect transistor (FET) biosensors are fabricated
and studied their properties in 1 mM phosphate-buffered
saline solution with pH = 7.4 using transport and noise
spectroscopy. At small VDS, the conventional current
behavior of FET with a linear dependence on voltage is
registered in the output current-voltage (I-VM)
characteristics with M=1. At drain-source voltage VDS > 0.6
V, the I-V characteristics with stronger power M are
revealed. It is shown that the current in LGAA NW FETs
follows current proportional to voltage in power M = 4
dependence on small liquid gate voltages. Transport and
noise spectroscopy analyses demonstrate that the obtained
results are associated with the space-charge-limited current
(SCLC) effect. Moreover, a strong two-level random telegraph
signal (RTS) is found in the region corresponding to SCLC at
VDS values exceeding 0.6 V. The RTS related to single trap
phenomena results in a well-resolved Lorentzian component of
noise spectra. The results demonstrate that the SCLC and
two-level RTS phenomenon are correlated effects. They should
be taken into account during the development of
single-trap-based devices, including biosensors.},
