abstract = {With the fast-shrinking of the transistor dimensions, the
low-frequency noise level considerably increases emerging as
an important parameter for the design of advanced devices
for information technologies. Single-trap phenomena (STP) is
a promising approach for the low-frequency noise suppression
technique in nanotransistor biosensors by considering
trapping/detrapping noise as a signal. We show a noise
reduction mechanism offered by STP in nanoscale devices
making the analogy with stochastic resonance effect found in
biological systems by considering a single trap as a
bistable stochastically driven nonlinear system which
transmits and amplifies the weak signals. The STP noise
suppression effect is experimentally demonstrated for the
fabricated liquid-gated nanosensors exploiting STP. We found
the optimal conditions and parameters including optimized
gate voltages to implement a stochastic switching effect for
the extraction of useful signals from the background noise
level. These results should be considered for the
development of reliable and highly sensitive nanoscale
biosensors.},
