Special Issue Information

Dear Colleagues,

The semiconductor industry is undergoing a revolutionary transition from conventional charge-based to emerging polarization-based computing paradigms. In this new era, system performance and energy efficiency are being redefined by the unique properties of ferroelectric components—including non-volatility, ultrafast switching speed, and nanoscale scalability. This transformative shift is being propelled by urgent technological demands in edge AI computing, ultra-low-power sensor networks, and next-generation non-volatile memory architectures.

We are now at a pivotal moment in ferroelectric materials research, witnessing remarkable innovations in hafnium-based ferroelectrics, 2D ferroelectric materials, and engineered multiferroic heterostructures that promise to redefine the landscape of modern electronics. This Special Issue is dedicated to showcasing and discussing the most significant advances in ferroelectric technologies, with particular focus on novel memory devices (FeRAM, FeFET, FTJ, Fe diodes), neuromorphic computing elements, piezoelectric sensors, and other emerging applications.

We enthusiastically welcome original contributions spanning fundamental research to technological applications, including but not limited to the following areas: discovery and optimization of new ferroelectric materials; advanced characterization of domain dynamics and switching mechanisms; device physics and reliability studies; innovative circuit design methodologies; and system-level integration. Particular attention will be given to interdisciplinary studies that synergize materials innovation with device engineering and system applications. We also encourage submissions featuring novel characterization techniques and computational modeling approaches for understanding complex ferroelectric phenomena.

Due to the Von Neumann bottleneck of traditional CMOS computing, there is an urgent need to develop in-memory logic devices with low power consumption. In this work, we demonstrate ferroelectric diode devices based on the TiN/Hf0.5Zr0.5O2/HfO2/TiN structure, implementing 16 Boolean logic operations through single-step or multi-step (2–3 steps) cascade and achieving attojoule-level one-bit full-adder computation. The TiN/Hf0.5Zr0.5O2/HfO2/TiN ferroelectric diode exhibits non-destructive readout and bidirectional rectification characteristics, with the conduction mechanism following Schottky emission behavior in the on-state. Based on its bidirectional rectification characteristics, we designed and simulated the circuit scheme of 16 Boolean logic and one-bit full-adder through cascaded operations. Both the input and output logic values are represented in the form of resistance, without the need for additional form conversion circuits. The state writing is performed by pulse-controlled polarization flipping, and the state reading is non-destructive. The logic circuits in this work demonstrate superior performance with ultralow computing power consumption in simulation. This breakthrough establishes a foundation for developing energy-efficient and scalable in-memory computing systems. Full article
