Prediction of the electronic structure of single-walled black phosphorus nanotubes
Literature Information

Due to its high carrier mobility and tunable bandgap, phosphorene has been the subject of immense interest recently. Herein, we show using density functional theory based calculations that black phosphorus (BP) nanotubes are achievable. Moreover, the electronic properties of BP nanotubes are explored. In contrast to their monolayer and bulk counterparts, most BP nanotubes possess indirect band gaps. In addition, strong anisotropic electronic behaviors are observed between zigzag and armchair nanotubes. Semiconducting to semi-metallic transition occurs only for zigzag tubes when its diameter shrinks to ∼1.5 nm. This difference is strongly related to the bond bending after the formation of the nanotubes which governs the s–p hybridization, as well as electron distribution in different p orbitals and this eventually determines the electronic structure of BP nanotubes.

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.
