日本語
ICTの電力消費削減に向け、HfZrO2ベースのFeFETをTCADシミュレーションで最適化。急峻なサブスレッショルド特性と低電圧動作により、電源電圧スケーリングで最大75%の動的電力削減が可能と推定。不揮発性により待機電力をほぼゼロにでき、データセンターのメモリ負荷での消費エネルギー削減に寄与する可能性を示す。ただし、持続可能性の効果はシナリオベースの推定値である。
English
This study optimizes HfZrO2-based FeFETs via TCAD simulations, achieving steep subthreshold switching and low-voltage operation, potentially reducing dynamic power by up to 75% through supply-voltage scaling. Non-volatile ferroelectric state enables near-zero standby power, suggesting reduced operational energy in data-center memory workloads. However, sustainability benefits are scenario-based estimates, not deployment-specific predictions.

📄 Abstract（原文）
The exponential growth of Information and Communication Technology (ICT), which already accounts for ~10% of global electricity consumption, demands ultra-low-power semiconductors and has the potential to align with decarbonization goals and sustainability targets. This study optimizes Hafnium Zirconium oxide (Hf₀.₅Zr₀.₅O₂)-based ferroelectric field-effect transistors (FeFETs) using 2D TCAD simulations of a metal-ferroelectric-insulator-semiconductor (MFIS) structure. The optimized device exhibits steep-subthreshold switching and low-voltage operation, indicating the potential for an ideal device-level dynamic power reduction of up to 75% through supply-voltage scaling, while the non-volatile ferroelectric state enables near-zero standby power at the memory-device level. Under the representative operating assumptions adopted in this study, these device-level improvements suggest the potential for reduced operational energy consumption in data-center memory workloads. Consequently, the proposed HZO-based FeFET architecture may contribute to lower ICT-related carbon emissions, although the reported sustainability benefits should be interpreted as scenario-based analytical estimates rather than deployment-specific predictions.
