报告摘要:New materials are essential and urgently needed for future technologies, but how to develop such materials in a fast and economical way is the challenge. Recently, materials Genome approach which integrates computational, data analytics and experimental research has emerged as a new paradigm for discovery of new materials. In this talk, besides an overview on this new paradigm and an outlook for the future, I will focus on our recent work in developing a materials genome for two-dimensional (2D) materials. 2D materials have attracted tremendous amount of interest because their unique properties are expected to lead to new technologies, including low power consumption, high efficiency energy storage and conversion devices. In an effort of systematic 2D materials discovery, we have been using both the top-down and the bottom-up approaches to generate 2D structures. On one hand, monolayer structures are theoretically exfoliated from layered three-dimensional structures by a topology-based algorithm. On the other hand, new 2D materials are systematically generated by chemical substitution of elements in known 2D compounds by similar elements. High throughput first-principles calculations are carried out to study their basic properties. The database, 2DMatPedia, is publicly available (http://www.2dmatpedia.org/) and provides a good starting point for further material screening, data mining, data analysis and artificial intelligence applications. A few materials design examples will be discussed, including high-throughput screening of transition metal single atom catalysts anchored on MoS2 for nitrogen fixation, high-throughput identification of exfoliable 2D materials with active basal planes for hydrogen evolution, high throughput computational screening of vertical 2D van der Waals heterostructures for high-efficiency excitonic solar cells, etc.
