abstract = {The basic reason for enhanced electron capture time, τc ,
of the oxide single trap dependence on drain current in the
linear operation regime of p+-p-p+ silicon field effect
transistors (FETs) was established, using a
quantum-mechanical approach. A strong increase of τc slope
dependence on channel current is explained using
quantization and tunneling concepts in terms of strong field
dependence of the oxide layer single trap effective
cross-section, which can be described by an amplification
factor. Physical interpretation of this parameter deals with
the amplification of the electron cross-section determined
by both decreasing the critical field influence as a result
of the minority carrier depletion and the potential barrier
growth for electron capture. For the NW channel of n+-p-n+
FETs, the experimentally observed slope of τc equals
(−1). On the contrary, for the case of p+-p-p+ Si FETs in
the accumulation regime, the experimentally observed slope
of τc equals (−2.8). It can be achieved when the
amplification factor is about 12. Extraordinary high capture
time slope values versus current are explained by the
effective capture cross-section growth with decreasing
electron concentration close to the nanowire-oxide
interface.},
