Description
Description
We screen all experimentally known inorganic materials in order to identify those that could be exfoliated into novel two-dimensional monolayers. The screening protocol first identifies compounds that appear layered, and characterizes with Van-der-Waals density-functional theory the energetics and electronic structure of the 3D parent and the exfoliated monolayer. The search is highly automated – thanks to the materials informatics platform AiiDA, that preserves the provenance for all data and workflows – and the results are openly disseminated on the Materials Cloud (https://www.materialscloud.org/discover/mc2d). We have identified ~3500 novel monolayers, of which ~2000 are classified as easily exfoliable, leading to suggestions for novel quantum spin Hall insulators (already confirmed experimentally), superconductors, and field-effect transistors.
