The doping effects of monolayer Ca2N on electronic states: A first-principles calculation

Chinese Science Bulletin 2025年第4-5期70卷 612-620页

作者： Miao, Yaping Guo, Mengsheng Xiao, Shuli Wu, Fan Fan, Wei School of textile Science and Engineering Xi’an Polytechnic University Xi’an710048 China Key Laboratory of Functional textile Materials and Products Ministry of Education Xi’an Polytechnic University Xi’an710048 China

Given the importance of two-dimensional (2D) materials in the development of microelectronic devices, condensed matter physics and chemistry concepts, the existence of electrodes with two-dimensional electronic structures has become a hot research direction. Two-dimensional calcium nitride (Ca2N) with a layered structure is a new type of 2D electrode materials, the conduction electrons are confined between Ca layers, and the 2D confined electrons behave as anions, showing the unique topological characteristics of electrode materials, which has potential applications in high-performance electronic devices and chemical synthesis. The space group of Ca2N belongs to R3m, and the layers are stacked along the direction of the c axis. The interaction between the layers is through the van der Waals force, and the weak molecular force between the layers makes the single layer Ca2N easy to be stripped from the body phase like graphene. But the influence of its electrical properties and its changing rules are not sufficiently studied. Doping can effectively regulate the electronic band structure and improve the integration of thin-layer two-dimensional materials, so as to accurately control and optimize various properties of materials. What’s more, doping not only regulates the band structure of the system, but also affects the magnetic properties of the system. It provides a novel approach for designing and constructing high-performance microelectronic devices. Therefore, the electrical properties of pure Ca2N and the regulation of doping on its electrical properties are studied by first principles calculation based on density functional theory. Calculations were conducted using the Vienna Ab-initio Simulation Package (VASP). The energy cutoff for the plane wave basis set was set to 500 eV, and the interactions between ionic cores and valence electrons were described using the projector augmented wave (PAW) method. For the exchange-correlation functional, the generalized grad

Fuhe Cailiao Xuebao/Acta Materiae Compositae Sinica 2025年第2期42卷 900-911页

A protonated graphite carbon nitride (P-g-C3N4) coated graphene oxide (GO) composite material (GO@Pg-C3N4) was prepared via electrostatic self-assembly method, and its application in photocatalytic antibacterial activities was investigated. The micro morphologyies, crystalline structures, and photoelectric properties of the GO@P-g-C3N4 composite material were characterized by SEM, TEM, XRD, XPS, Raman, UV-Vis DRS and steady-state/transient fluorescence spectroscopy (PL), etc. The structure of GO@P-g-C3N4 composite material was optimized by adjusting the content of P-g-C3N4. Under simulated solar light irradiation conditions, E. coli and S. aureus were used as experimental targets to study the photocatalytic antibacterial performance of GO@P-g-C3N4 composites with different P-g-C3N4 contents and the influence of irradiation times on antibacterial performance. It was found that GO@P-g-C3N4-80% composite material synthesized with a mass ratio of 1∶4 between GO and P-g-C3N4 exhibited antibacterial rates against E. coli and S. aureus of 98.80% and 95.99%, respectively after 100 min of illumination. After 150 min of illumination, antibacterial rates against both E. coli and S. aureus exceeded 99%, demonstrating significantly better antibacterial performance compared to individual GO or P-g-C3N4 © 2025 Beijing University of Aeronautics and Astronautics (BUAA).
