“…The chemical synthesis of phosphorene has many advantages such as good crystallinity and high purity. Although chemical bottom-up methods have not made a breakthrough, the rapid development of chemical vapor deposition substrate creates a promising future for phosphorene chemical growth [45]. The requirement for high quality, strong controllability and efficiency will further increase with the development of the field of nanoelectronics.…”

Abstract:In recent years, a new 2D-layered material-black phosphorus (BP)-has been a rising star after the era of graphene owing to its high charge carrier mobility, tunable direct bandgap and unique in-plane anisotropic structure. With the development of the synthesis and modification methods of BP, its extensive applications, e.g., transistors, batteries and optoelectronics have emerged. In order to explore its full potential, research into the tribological properties of BP 2D-layered materials such as lubrication additives and fillers in self-lubricating composite materials would be not only of high scientific value but also of practical significance. In this work, recent advances on the friction and lubrication properties of BP nanosheets made by our group, including the micro-friction properties, the lubrication properties of BP nanosheets as water-based and oil-based lubrication additives, and the friction and wear of BP/PVDF composites will be presented. Finally, the future challenges and opportunities in the use of BP materials as lubricants will be discussed.

“…The material bridges the gap between gapless graphene and wide‐band gap transition‐metal dichalcogenides . Owing to its unique structure and properties, LBP shows excellent performance as electronic or optoelectronic devices, sensors, catalysts, etc . However, practical applications of LBP are seriously challenged by its low stability in the presence of O 2 and/or H 2 O. Bare LBP can rapidly transform into oxides (P x O y ), and further decompose into acids or salts (e.g.…”

The practical application of layered black phosphorus (LBP) is compromised by fast decomposition in the presence of H2O and/or O2. The role of H2O is controversial. Herein, we propose a hydroxide ion (OH−)‐initiated degradation mechanism for LBP to elucidate the role of H2O. We found that LBP degraded faster in alkaline solutions than in neutral or acidic solutions with or without O2. Degradation rates of LBP increased linearly from pH 4 to 10. Density functional theory (DFT) calculations showed that OH− initiated the decomposition of LBP through breaking the P−P bond and forming a P−O bond. The detection of hypophosphite, generated from OH− reacting with P atoms, confirmed the hypothesis. Protons acted in a way distinctive from OH−, by inducing deposition/aggregation or forming a cation–π layer to protect LBP from degradation. This work reveals the degradation mechanism of LBP and thus facilitates the development of effective stabilization technologies.

“…Recent success in growing two-dimensional, hexagonal "postgraphene" systems [5], including BP monolayers (so-called phosphorene) [6,7], has also intensified the interest in understanding its electronic structure [8,9] and transport properties [10]. BP is the thermodynamic stable allotrope of elemental phosphorus [11], and its layered structure is unique among the elements.…”

We investigate anisotropic electronic structure and thermal transport properties of bulk black phosphorus (BP). Using density functional dynamical mean-field theory we first derive a correlation-induced electronic reconstruction, showing band-selective Kondoesque physics in this elemental p-band material. The resulting correlated picture is expected to shed light onto the temperature and doping dependent evolution of resistivity, Seebeck coefficient, and thermal conductivity, as seen in experiments on bulk single crystal BP. Therein, large anisotropic particle-hole excitations are key to consistently understand thermoelectric transport responses of pure and doped BP.
