SYTS 1: Interaction effects and correlations in twodimensional systems - New challenges for theory

SYTS 1.5: Invited Talk

Wednesday, April 3, 2019, 17:15–17:45, H1

High-throughput modeling and discovery of novel 2D materials — •Kristian Thygesen — Technical University of Denmark, Lyngby, Denmark

I will discuss how the electronic and optical properties of general 2D materials and their heterostructures can be accurately predicted by combining classical electrostatic models with many-body quantum mechanics and high-performance computing. I will give examples from our recent research focusing on 2D structures with tunable band energies, excitons, and plasmons[1]. Finally, I will present our recent efforts to establish a comprehensive database of 2D materials using an automatic high-throughput framework (http://c2db.fysik.dtu.dk) and show how it can be used to identify novel 2D materials with interesting physical properties such as ferromagnetism and non-trivial topology[2].
