Query: Artificial Intelligence for High-Throughput Discovery of Topological
  Insulators: the Example of Alloyed Tetradymites   Significant advances have been made in predicting new topological materials
using high-throughput empirical descriptors or symmetry-based indicators. To
date, these approaches have been applied to materials in existing databases,
and are severely limited to systems with well-defined symmetries, leaving a
much larger materials space unexplored. Using tetradymites as a prototypical
class of examples, we uncover a novel two-dimensional descriptor by applying an
artificial intelligence (AI) based approach for fast and reliable
identification of the topological characters of a drastically expanded range of
materials, without prior determination of their specific symmetries and
detailed band structures. By leveraging this descriptor that contains only the
atomic number and electronegativity of the constituent species, we have readily
scanned a huge number of alloys in the tetradymite family. Strikingly, nearly
half of which are identified to be topological insulators, revealing a much
larger territory of the topological materials world. The present work also
attests the increasingly important role of such AI-based approaches in modern
materials discovery.
