要旨

The mechanism underlying bipolar charge distribution in the context of triboelectrification remains ambiguous. Furthermore, water can either promote or inhibit triboelectrification. It was determined through experimental and first-principles calculations that water can also reverse the polarity of transferred charges and cause a bipolar charge transfer. We examined triboelectrification between an Au/Cr-coated tip and stoichiometric Si3N2 film using Kelvin probe force microscopy. In addition, we investigated the generation of a bipolar charge distribution on the insulating Si3N2 surface by controlling the frictional conditions. With regard to the effect of a water meniscus in the interface between the surface and tip, we predicted the dissociation of water molecules on the Si3N2 surface and polarity reversing induced by water via first principles. Finally, we focused on the effect of water on the dangling bonds of Si atoms and surface states of Si3N2. The results indicated that the dangling bonds and surface states are essential to a bipolar charge transfer.

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.
