We have investigated the structures, electronic structures and magnetic properties of the triazine-based g-C3N4 (gt-C3N4) monolayer doped with B, Al, and Cu atoms based on density functional theory using ab initio calculations. The B atom prefers to be situated at the center of the triazine ring, whereas the Al and Cu atoms tend to be located above the center of the triazine ring. The doping at the interstitial sites results in nonplanar structures which are thermodynamically stable. Each dopant atom induces a total magnetic moment of 1.0 μB which mainly arises from the pz orbitals because the n-type doping injects unpaired electrons into anti-π orbitals. The results obtained from the GGA-PBE and HSE06 schemes show that all the doped systems exhibit half-metallic behaviors. B- and Al-doped systems are at a ferromagnetic ground state, while the Cu-doped case is at an anti-ferromagnetic ground state. The long-range half-metallic ferromagnetic order is attributed to the p–p interactions. In particular, the estimated Curie temperature implies that the systems doped with B are potential candidates for spintronics applications in future.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
