Meanwhile, the quest of a sustainable society has stimulated resource-conscious and environmental-friendly energy technologies. In Thrust III, we 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 and energy-efficient spintronic devices. 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. There are 10 PIs dedicated to this thrust, Dr. Li-Chyong Chen, Dr. Michitoshi Hayashi, Dr. Leeyih Wang, Dr. Jauyn Grace Lin, Dr. Juen-Kai Wang, Dr. Chih-Wei Chang, Dr. Heng-Liang Wu, Prof. Hung-Hsiang Cheng, Prof. Hsuen-Li Chen, and Prof. Chi-Feng Pai. Specifically, four experimental-based topics and one theoretical framework will be addressed in the years to come, with the coherent goal of unraveling the structure-property correlation behind each material system.原子分子級材料應用;Atomic/Molecular Functionalization of New Materials and Theoretical Framework國立臺灣大學高等教育深耕計畫-特色領域研究中心 【子計畫三:碳中和:關鍵材料開發、理論計算與反應機制】
