Topological quantum chemistry and symmetry-based indicators have facilitated large-scale
searches for materials with topological properties at the Fermi energy (EF). We report the …

The present pin perovskite solar cells are less efficient than their nip counterparts,
fundamentally limited by deep-level traps of minority carriers at surfaces. Here, we explore …

Rutile RuO 2 has been posited as a potential d-wave altermagnetism candidate, with a
predicted significant spin splitting up to 1.4 eV. Despite accumulating theoretical predictions …

Stable and efficient perovskite/silicon tandem solar cells require defect passivation and
suppression of light-induced phase segregation of the wide-band-gap perovskite. Here, we …
