Why Does It Get Hot When You Rub Things Together? Unraveling the Mystery of Dynamic Friction at the Atomic Level (IMAGE)
Caption
Figure 1: Dynamic friction at an atomic level. (A) Illustration of the CO molecule being manipulated on a copper surface by a metal tip. (B) Changes in the CO molecule's adsorption states while the tip moves horizontally across the surface. The interaction energies between the tip and CO are represented by different lines: CO on the top site (black curve), on the bridge site (red curve), and on the neighboring top site (blue curve). As the tip progresses, the actual adsorption state of CO follows the solid lines. The transitions between different adsorption sites (green cross) provide key insights into the intricacies of dynamic friction.
