Superlubricity of graphene nanoribbons on gold surfaces
Superlubricity of graphene nanoribbons on gold surfaces
The state of vanishing friction known as superlubricity has important applications for energy saving and increasing the lifetime of devices. Superlubricity detected with atomic force microscopy appears in examples like sliding large graphite flakes or gold nanoclusters across surfaces. However, the origin of the behavior is poorly understood due to …
