Altermagnetism-Induced Spin-resolved electronic structure in Janus FeX0.5Y0.5 Monolayers (X, Y = S, Se, Te)
Mengyang Zhang, Jie Li, Yifei Chen +3
Realizing the spin-resolved electronic properties in superconducting materials stands as a critical frontier, offering both novel fundamental physics and potential for dissipationl…
High-Throughput Discovery of Semimetallic Borophenes with Diverse Dirac States Via Transferable Tight-Binding Approach
Yuke Song, Shifang Li, Tao Ouyang +3
Borophene has attracted extensive interest due to its structural flexibility and emergent topological electronic states. However, semimetallic borophenes hosting robust Dirac state…
Stacking-Engineered Switchable Altermagnetism in Topological FeSe bilayer systems
Jie Li, Shifang Li, Mengyang Zhang +3
Altermagnetism and topological insulators represent two of the most transformative frontiers in modern condensed matter physics, spintronics, and quantum information science. Bring…
Domain-Direct Band Gaps: Classification and Material Realization
Yalan Wei, Hairui Ding, Shifang Li +4
The conventional classification of direct band-gap semiconductors relies on point-like extrema in momentum space. Here, we introduce the concept of domain-direct band gaps, where t…
Two-dimensional flat-bands in Moire-diamonds
Yalan Wei, Shifang Li, Yuke Song +1
The discovery of flat-bands in magic-angle twisted bilayer graphene has underscored the potential of moire engineering for correlated states, but such phases are notoriously diffic…
First-principles predictions of the diversity in atomic structures and electronic properties of the reconstructed Si(111)-7x7 surface
Yuke Song, ShiFang Li, PeiZe Lin +4
The 7x7 reconstruction of Si(111) surface is widely understood by the dimer-adatom-stacking-fault model (DAS), but the predicted metallicity of DAS contradicts experimental signs o…
