The objective of the proposed research is to study the impact of domains on negative capacitance and phase transitions in fluorite and perovskite-structure ferroelectrics. In today’s digital landscape, the proliferation of Internet of Things (IoT) devices has led to an unprecedented generation of data. Furthermore, the evolution of artificial intelligence (AI) algorithms has become increasingly complex, demanding substantial computing power to train and execute these advanced models effectively. However, this surge in data and the computing power required to process it has outpaced the advancements in transistor technology where the continuous miniaturization of transistors to increase computational power, as predicted by Moore’s Law, is becoming increasingly challenging due to physical and technological constraints. To address these challenges, we propose leveraging negative capacitance as a potential solution. Negative capacitance holds immense promise in overcoming the power and energy limitations through ultra-low power and high frequency operations.
