High-throughput study of electrical conductivity in ordered metals
Thalis H. B. da Silva, Hai-Chen Wang, Tiago F. T. Cerqueira +3
We present a computational framework that integrates machine learning with high-throughput ab initio calculations to screen over 2.8 million compounds for metallic transport. We id…
Optical selection rules in hexagonal Ge polytypes and their lifting by symmetry perturbation
Martin Keller, Haichen Wang, Friedhelm Bechstedt +2
Hexagonal germanium polytypes have emerged as promising direct-gap semiconductors for silicon-integrated optoelectronics, yet their optical properties remain largely unexplored bey…
AI-Driven Expansion and Application of the Alexandria Database
Théo Cavignac, Jonathan Schmidt, Pierre-Paul De Breuck +9
We present a novel multi-stage workflow for computational materials discovery that achieves a 99% success rate in identifying compounds within 100 meV/atom of thermodynamic stabili…
Generative AI for Crystal Structures: A Review
Pierre-Paul De Breuck, Hai-Chen Wang, Gian-Marco Rignanese +2
As in many other fields, the rapid rise of generative artificial intelligence is reshaping materials discovery by offering new ways to propose crystal structures and, in some cases…
High-throughput study of kagome compounds in the AV3Sb5 family
Thalis H. B. da Silva, Tiago F. T. Cerqueira, Hai-Chen Wang +1
The kagome lattice has emerged as a fertile ground for exotic quantum phenomena, including superconductivity, charge density waves, and topologically nontrivial states. While AV3Sb…
A non-orthogonal representation of the chemical space
Tiago F. T. Cerqueira, Haichen Wang, Silvana Botti +1
We present a novel approach to generate a fingerprint for crystalline materials that balances efficiency for machine processing and human interpretability, allowing its application…
