Unusual strain relaxation and Dirac semimetallic behavior in epitaxial antiperovskite nitrides
Ting Cui, Zihan Xu, Qinghua Zhang +13
Antiperovskite nitrides (X3AN) are the structural analogues to perovskite oxides, while their epitaxial growth and electronic properties remain largely unexplored. We report the su…
Observation of square-like moire lattice and quasicrystalline order in twisted rock-salt nitrides
Dongke Rong, Qinghua Zhang, Ting Cui +10
Twistronics, which exploits moire modulation of lattice and electronic structures in twisted bilayers, has emerged as a powerful approach to engineer novel quantum states. Recent e…
Advancing Antiferromagnetic Nitrides via Metal Alloy Nitridation
Qianying Wang, Zexu He, Lele Zhang +14
Nitride materials, valued for their structural stability and exceptional physical properties, have garnered significant interest in both fundamental research and technological appl…
Room-temperature magnetoelectric coupling in strontium titanate
Zhen Yang, Cheng Ma, Mengqin Wang +12
Magnetoelectric (ME) multiferroics enable efficient interconversion of electrical and magnetic signals, offering pathways toward substantial reduction of power consumption in next-…
Deteriorated Interlayer Coupling in Twisted Bilayer Cobaltites
Dongke Rong, Xiuqi Chen, Shengru Chen +15
A wealth of remarkable behaviors is observed at the interfaces between magnetic oxides due to the coexistence of Coulomb repulsion and interatomic exchange interactions. While prev…
A single-phase epitaxially grown ferroelectric perovskite nitride
Songhee Choi, Qiao Jin, Xian Zi +21
The integration of ferroelectrics with semiconductors is crucial for developing functional devices, such as field-effect transistors, tunnel junctions, and nonvolatile memories. Ho…
