New Zero Power Memristor Emulator Model and Its Application in Memristive Neural Computation

IEEE Access, 2023
We present here a simple three P-type MOSFET-based grounded memristor emulator model. The model is designed to achieve zero static power dissipation and is done so by eliminating the external DC supply i.e., no DC bias.

Origin of pinched hysteresis in PbZrO3-PbTiO3-PbHfO3 and its restoration to typical ferroelectric hysteresis

Discover Applied Sciences
Ferroelectric materials typically exhibit single-loop hysteresis with substantial remnant polarization, while the anti-ferroelectric materials show double-loop hysteresis with zero remnant polarization.

Electric-field-induced phase transition and pinched P–E hysteresis loops in Pb-free ferroelectrics with a tungsten bronze structure [PDF]

NPG Asia Materials, 2018
Antiferroelectrics are of interest due to their high potential for energy storage. Here, we report the discovery of pinched, polarization-vs.-electric field (P–E) hysteresis loops in the lead-free tungsten bronze ferroelectrics Ba4Sm2Ti4Nb6O30 and Ba4Eu2Ti4Nb6O30, while a broad, single P–E hysteresis loop was observed in the analogue compound ...

Multiferroic‐Centric Materials and Systems Engineering for Battery Applications: An Insight Into Mechanisms, Strategies, and Characterizations

Advanced Science, EarlyView.
Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses
