“…6(d) presents the results of the assessments over the total drive cycle with PNZST samples compared to previous results. 1,9 The net mean power was 40.8 mW cm À3 (accumulated generating energy of 49 117.4 J L À1 ), which is the highest value produced by any material in our energy harvesting system to date 1,[9][10][11][12] and is 314 times greater than what we presented in our rst report. 1 The comparisons of the current maximum power and energy density for pyroelectric energy harvesting studies for various materials are shown in Table 2, together with the respective operating conditions.…”

“…This may be related to the fact that the switching of the ferroelectric domain is affected by temperature. [ 23 ] At high temperature range (300–440 K), I OFF slightly increases compared to the ones at low temperatures, which could be related to the increase in thermal noise. However, when the temperature is higher than 420 K, the switching behavior of crack gradually disappears with the increase of temperature that may exceed the Curie temperature of PMN‐PT.…”

Ferroelectric devices have attracted intensive research in memory and logic applications due to their non‐volatility, scalability, and energy efficiency. As an emerging technology, the ferroelectric nanocrack device offers a simple and efficient way to manipulate the device resistance states with a high on/off ratio. Meanwhile, its complementary switching enables the construction of logic gates with a similar way as the complementary metal oxide semiconductor (CMOS) technology. Here, it is demonstrated that the memory and logic functions can be realized by the same device structure with superior electrical performance, such as reliable metallic on‐state contacts, zero off‐state leakage current, and wide working temperature range (–110 to 150 °C). Moreover, the scaling performance has been investigated and the operating voltage can be reduced to average 2.5 V with device scaling down to sub‐micrometers. Following the scaling rule, the operating voltage can shrink largely to sub‐1 V at 100 nm nodes. In addition, the logic gates including NOT, 2:1 MUX, AND, and OR functions have been experimentally demonstrated. It is believed that this work can expand the scope of ferroelectronics and be applicable to logic‐in‐memory computing in the future.

Ba(Ti1‐xHfx)O3 ceramics were synthesized by a solid‐state reaction process. The evolution of the phase structure was identified by XRD spectrum, dielectric spectroscopy, and temperature‐dependent Raman spectroscopy for the Ba(Ti1‐xHfx)O3 ceramics. In addition, pyroelectric energy harvesting properties based on the Olsen cycle were investigated for the first time. A maximum pyroelectric energy harvesting density value of ND = 491.30 kJ/m3 (ΔT = 120°C, EH = 50 kV/cm) was achieved in the Ba(Hf0.05Ti0.95)O3 ceramic. Compared with those of BT, the values of ND more than doubled in the temperature range from ΔT = 60°C to ΔT = 100°C in the Ba(Hf0.05Ti0.95)O3 ceramic and even increased 3.2 times at ΔT = 80°C near the Curie temperature (TC) of the Ba(Hf0.05Ti0.95)O3 sample. In addition, a larger pyroelectric energy harvesting density value of ND = 367.10 kJ/m3 (ΔT = 120°C, EH = 50 kV/cm) was acquired in the Ba(Hf0.12Ti0.88)O3 ceramic. Values of ND‐BHT5/ND‐BT and ND‐BHT12/ND‐BT were analyzed in the Ba(Ti1‐xHfx)O3 ceramics. The optimal pyroelectric properties can be obtained in the vicinity of the ferroelectric to paraelectric phase‐transition region.
