Article Synopsis
  • Structural superlubricity (SSL) is a state of extremely low friction and wear between solid surfaces, providing a potential solution for reducing these factors in practical applications.
  • Recent research identifies that edge pinning significantly influences SSL friction, although understanding of its atomic-level nature was previously unclear.
  • The study reveals the atomic structure of disordered edges in microscale graphite and demonstrates that by using SiN caps to disconnect edges from the substrate, an ultra-low friction stress of 0.1 kPa or lower can be achieved.
