Guidelines for band gap opening in graphene superlattices with periodic Ï-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…
Localized Exciton Emission with Spontaneous Circular Polarization in NiPS3/WSe2 Heterostructures
Adi Harchol, Shahar Zuri, Rajesh Kumar Yadav +7
Two-dimensional (2D) van der Waals (vdW) heterostructures (HSs) provide a versatile platform for tailoring electronic, optical, and magnetic properties via proximity effects at the…
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…
Crystal Anisotropy Implications on the Magneto-Optical Properties of van der Waals FePS3
Ellenor Geraffy, Kusha Sharma, Shahar Zuri +10
Antiferromagnetic FePS3 has recently gained significant interest in its potential applications in spin-related devices. Here, we show that in-plane structural anisotropy has a majo…
Suppressed excitonic effects enable high mobility, high-yield photoconductivity in a two-dimensional polymer crystal with axial pyridine coordination
Shuai Fu, Ye Yang, Guoquan Gao +8
Two-dimensional polymers (2DPs) and their layer-stacked covalent organic frameworks (2D COFs) offer modular, atomically precise platforms for organic optoelectronics, yet their pho…
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 Ï-ele…
