abstract = {We report electrical characterization of memory elements
consisting of a p-type silicon field-effect transistor
incorporating a ferroelectric polymer Langmuir-Blodgett film
into the gate insulator to produce bistability through
polarization hysteresis. The thin gate insulator, consisting
of a 10 nm thick silicon oxide layer and a 35 nm thick
ferroelectric polymer film, enabled bistable operation at 4
V. Device hysteresis as a function of gate voltage was
evident both in the device capacitance, which was measured
between the gate and drain, and in the source-drain
conductance. The ferroelectric film polarization was not
saturated, even up to operating voltages of 10 V. This is
likely the reason for the short state retention of less than
10 s at room temperature. The hysteresis vanished as the
sample was heated toward the ferroelectric-paraelectric
phase transition temperature, showing that the bistability
was due to ferroelectric polarization reversal. (c) 2010
