Outline of Final Research Achievements

Ultrathin films with high-k dielectric/ferroelectric properties form the basis of modern electronics. With the further miniaturization of electronic devices, conventional materials are expected to experience challenge because of their critical thickness, where the dielectric/ferroelectric responses are unstable or even disappeared if the film thickness is reduced to the nanometer scale or below a two-dimensional (2D) limit. In this study, we try to explore 2D dielectrics/ferroelectrics and related device applications. Through detailed investigations on critical properties at 0.5~3 nm scale, we clarified dielectric/ferroelectric responses at 2D limit, and discovered new high-k dielectric/ferroelectric nanosheets. We also utilized layer-by-layer engineering of 2D nanosheets, and successfully developed 2D capacitors/FETs with improved performances.
