Guidelines for band gap opening in graphene superlattices with periodic π-vacancy distribution
Diyan Unmu Dzujah, Hongde Yu, Thomas Heine
Periodic -vacancies in graphene superlattices (GSLs) provide a symmetry-based route to band-gap opening in graphene by modifying the -band dispersion. However, the symmetry c…
Designer metal-free altermagnetism in honeycomb two-dimensional frameworks
Hongde Yu, Thomas Brumme, Thomas Heine
Altermagnetism combines momentum-dependent spin splitting of opposite-spin channels with zero net magnetization, enabling electric-field control of spin transport that is robust ag…
Metal-Free Room-Temperature Ferromagnetism
Hongde Yu, Thomas Heine
Achieving robust room-temperature ferromagnetism in purely organic 2D crystals remains a fundamental challenge, primarily due to antiferromagnetic (AFM) coupling mediated by π-elec…
Metal-free Stoner and Mott-Hubbard magnetism in 2D polymers with honeycomb lattice
Hongde Yu, Thomas Heine
We computationally demonstrate Stoner-ferromagnetic half-metals and antiferromagnetic Mott-Hubbard insulators in metal-free 2D polymers. Coupling radicaloid (hetero)triangulene mon…
