Friction, the force that resists
becomes crucial for the intriguing concept of structurallubricity, where collective force cancellation effects can result in ultra-low friction for incommensurate interfaces [39][40][41]. Note that “superlubricity” and “structurallubricity” are often used synonymous throughout the literature, although
the latter term should be considered to be more accurate [42].
The experimental analysis of structurallubricity has long since been difficult, because well-defined junctions between conventional AFM tips and substrates cannot readily be found for single-asperity contacts. Instead, the detailed
