Abstract for Presentation

Ubiquitous interlayer coupling in 2D materials and its effects on materials properties



   Two-dimensional (2D) layered materials have attracted increasing intense interest because of their unique mechanical, electronic and optical attributes. Interlayer coupling is a ubiquitous phenomenon residing among the atomically thin 2D layers. For different 2D materials, it may be dominated by the weak van der Waals interaction or by the long-range electrostatic Coulomb interaction. The interlayer coupling controls monolayer exfoliation process and assembly of 2D heterostructures, and behaves as a unique degree of freedom for engineering 2D materials properties. With dramatically increasing computing capability of supercomputers and continuously developed computational algorithms, people can resort to materials simulation to explore the properties of thousands of potentially useful materials in a fraction of time that the real experiments might take. This makes theoretical design of functional materials with desired properties in computers come true. In this talk depending on time I will present our development on open-source artificial-intelligence-aided data-driven infrastructure named Jilin Artificial-intelligence aided Materials-design Integrated Package (JAMIP, and our recent work on computational design of new 2D materials and band structures engineering toward improved performance of 2D materials by exploiting the ubiquitous interlayer coupling effect.
