FIG. 4.

(a) -dependence of pyroelectric current in the -range of 10–100 K. (b) -dependence of under a series of warming speeds (2, 4, and 6 K/min) in the -range of 10–100 K. (c) -dependence of in the -range of 10–100 K with an electric field (5 kV/cm) applied along the thickness direction. The inset indicates in the -range of 10–40 K. (d) -dependence of under a positive or negative poling electric field (±5 kV/cm), over a range of .
