high-throughput search of novel 2d materials for electronic and optoelectronic applications — •davide campi, thibault sohier, antimo marrazzo, marco gibertini, nicolas mounet, and nicola marzari — Theory and simulation of materials (THEOS) and national center for computational design and discovery of novel materials (MARVEL), école polytechnique fédéral lausanne, ch-1015, lausanne, switzerland

2D materials provide a novel paradigm and toolbox for materials scientists to discover or engineer new properties and functionalities. However, the handful of 2D materials intensively studied up to now represent only a few of the manifold possibilities. In this work we present the results of an applications-oriented screening that, using state-of-the-art first-principles simulations and automatized high-throughput calculations through the AiiDA platoform[1], identifies new promising candidates for field effect transistors (FET), photocatalytic water splitting and nanoporous crystalline membranes, selected among the hindreds of 2D materials (1844)[2] discovered by performing a "computational exfoliation" of a dataset of more than 100000 bulk parent structures.
