The AI-Mat research hub will be based on the Center for Condensed Matter Sciences, which is the only hard center at university level in National Taiwan University (NTU), and integrate more experts in the field to focus on three thrust areas: (1) new materials growth by atomic design, (2) expert system on atomic material characterizations, and (3) atomic/molecular functionalzation of new materials and applications. The ultimate goal of the AI-Mat is to cast the opportunity of New Materials Made in Taiwan. Based on the world-leading crystal growth experience and technique established at NTU, Thrust I will establish a platform for new materials growth by atomic design and mainly focus on 2D layered single crystals, 2D atomic layered materials and novel atomic architectures. For Thrust II, the expert system on atomic material characterizations incorporates three spectro-microscopy techniques, atomic-scale scanning transmission electron microscopy, atomic-resolution scanning tunneling microscopy, and ultrafast optical spectroscopy. The integration of this framework is capable of achieving the spatial resolution from mesoscopic to atomic scales, the temporal resolution from static to femtosecond domains, and the optimal energy resolution down to few tens of meV, i.e., covering the general spatial, temporal, and energy regimes of most phenomena. As Moore’s Law has reached its limit, revolutionary technologies to the industry are expected in the new era of atomic scale. Development of novel materials and advanced spectroscopies and microscopies has enabled innovative technologies in an unprecedented manner. Meanwhile, the quest of a sustainable society has stimulated resource-conscious and environmental-friendly energy technologies. Here in Thrust III, we would like to focus on the atomic and molecular functionalities of new materials; in particular, our aims are to reduce greenhouse gas emissions, recycle waste heat, in the same time introduce renewable energy sources (such as solar fuels and thermoelectrics), as well as develop efficient and durable batteries, energy-efficient spintronic devices and key materials for sustainable economics. Though seemingly diversified properties to investigate, manipulation of the materials and interfaces in the atomic and molecular level holds the key for optimizing their functionalities towards the targeted applications. For such demanding endeavors, it is very important to incorporate a theoretical framework, which will not only concertedly establish comprehensive structure-property-performance correlation with the experimental efforts, but also proactively develop guiding principles based on the theoretical inputs. As importantly, we shall own the original and key technologies/patents."新穎材料原子級科學研究中心Center of Atomic initiative for new materials
