FIG. 1.

(a) Structure of the all-trans conformation of the ferroelectric phase. (b) A diagram of experimental setup used in x-ray diffraction measurements.

Image of FIG. 2.
FIG. 2.

Temperature dependence of (a) the capacitance, (b) (110) crystal spacing perpendicular to the sample surface, and (c) the integrated intensities of x-ray diffraction peaks from a 50-monolayer Langmuir–Blodgett film of P(VDF-TrFE). The circles (●) and squares (◼) represent the paraelectric and ferroelectric phases, respectively.

FIG. 3.

Temperature dependence of the x-ray diffraction data recorded from a 50-monolayer P(VDF-TrFE) sample upon (a) heating and (b) cooling.

Image of FIG. 4.
FIG. 4.

(a) Temperature-dependent capacitance data recorded from a 30-monolayer P(VDF-TrFE 70:30) sample at five different values of applied voltage. (b) The temperature of the peak capacitance for heating (●) and cooling (◼) plotted as a function of applied voltage.
