标题： Frictional Dissipation and Scaling Laws at van der Waals Interface: The Key Role of Elastic Pinning of Moiré at Edges and Corners

摘要： 范德华异质界面是实现结构超润滑扩展以满足实际应用的有前途的候选材料。 然而，已确定几个可能消除超润滑性的因素。 弹性是一个这样的内在因素，其中剪切引起的晶格重构会导致局部界面钉扎，即使在干净的原始接触中也是如此。 在此，通过详细的原子模拟，我们揭示了有限滑块角落和边缘的不完全莫尔晶格钉扎主导了从纳米到微尺度的摩擦。 我们进一步证明，滑块形状的调整和扭转可以控制能量耗散及其与接触尺寸的尺度关系，从而为实现大规模超润滑开辟了道路。 显示英文摘要

摘要： Van der Waals heterogeneous interfaces are promising candidates for the scaling up of structural superlubricity to meet practical applications. Several factors, however, have been identified that may eliminate superlubricity. Elasticity is one such intrinsic factor, where shear induced lattice reconstruction leads to local interfacial pinning, even at clean pristine contacts. Here, through detailed atomistic simulations, we reveal that incomplete moir\'e tile pinning at the corners and edges of finite sliders dominates friction from the nano- to the microscales. We further demonstrate that slider shape tailoring and twisting allow to control energy dissipation and its scaling with contact size, thus opening the way to achieve large-scale superlubricity.
