• Prague 6, Czech Republic 10.3762/bjnano.17.71 Abstract Achieving rapid and flexible control of friction across different material surfaces is of great significance and remains a longstanding challenging goal in modern tribology. Here, we demonstrate dynamic structural superlubricity in monolayer MoS2

• phononic friction model, reveal that torsional vibrations reduce energy barriers and promote transitions between atomic sites. This strategy provides a universal and reversible approach for active friction control at the nanoscale. Keywords: atomic force microscopy (AFM); dynamic structural superlubricity

• a dynamic structural superlubricity state. To systematically investigate the frequency dependence of the dynamic structural superlubricity, a frequency sweep from 0 to 625 kHz was performed with 256 sampling points (Figure 2a). The recorded tip vibration amplitude during frequency sweep and the mean
