Outline of Final Research Achievements

We demonstrate for the first time the flash memory operation of the interface dipole modulation by using multi-stack HfO2/SiO2 structures. Good program/erase endurance over 100,000 cycles has been demonstrated, and analog current characteristics useful for neuromorphic applications have been observed. Experimental evidence for interfacial dipole modulation has been shown by hard x-ray photoelectron spectroscopy studies, and rearrangement of interfacial bonding by an electric field has been theoretically demonstrated to induce the potential change in the HfO2/SiO2 system.

Academic Significance and Societal Importance of the Research Achievements

界面ダイポール変調は、代表者が提案したMOS (metal oxide semiconductor) 構造を用いたメモリ動作原理で、MOSキャパシタの特性からは動作実証されていたが、MOS FET (field effect transistor)に組み込んで動作させるフラッシュ型メモリは本研究が初めてとなる。硬 X 線光電子分光法による印加電圧下のその場観察も初めての実験であり、第一原理計算によるポテンシャル変調機構の議論は学術的価値が高いと考えている。また、新規不揮発メモリは巨大市場が約束されており、現在、世界中で研究開発が活発になっている。
