Abstract
In this study, we investigated the friction mechanisms behind the observed changes in friction of niobium diselenide (NbSe2) thin films under varying normal bias voltages. The results show that both the friction force and coefficient of friction (COF) increase with the application of positive and negative bias voltages. These friction changes are significantly affected by the electrostatic force on the sample surface and the electronic excitation during friction leads to energy dissipation, ultimately increasing friction. These findings not only increase our understanding of the interfacial friction phenomenon of nano-electric friction, but also help to control energy dissipation of sliding nanofriction, making electronic control of friction possible.
期刊介绍：
Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International.
Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
