Friction of graphene on a substrate with a cavity defect

引用

Science China Technological Sciences 2024年第9期67卷 2834-2841页

作者： ZHOU Peng huo ZhanLei CHANG TienChong Shanghai Institute of Applied Mathematics and Mechanics Shanghai Key Laboratory of Mechanics in Energy EngineeringShanghai Frontier Science Center of MechanoinformaticsSchool of Mechanics and Engineering ScienceShanghai University The Center for Computational Mechanics and Engineering Applications Provincial Mechanics Experimental Teaching Demonstration CenterSchool of Civil EngineeringHebei University of Engineering Shanghai Institute of Aircraft Mechanics and Control Tongji University Joint-Research Center for Computational Materials Zhejiang Laboratory

The frictional behavior of supported graphene is known to be influenced by the physical properties and surface morphologies of the underlying substrate. However, it is unclear how a surface defect on the substrate affects the friction of supported graphene,and it is even unknown how to define the defect-induced friction force in this context. Here we conduct molecular dynamics(MD) simulations to investigate the friction between a square diamond slider and a graphene sheet supported by a copper substrate with a surface cavity defect. Our results demonstrate that the defect-induced friction exhibits a nonlinear increase with cavity size, while it decreases nonlinearly with slider size. We propose that the definition of defect-induced friction can be linked to the increase in friction work over the length of the slider, and is closely correlated to the defect-induced relative change in indentation depth and the ratio of the cavity area to the contact area. These findings provide a comprehensive evaluation of the impact of a substrate cavity defect on the friction of supported graphene and offer insights that may have broader implications for understanding defect-induced friction in other two-dimensional materials.

Within a framework of this model, we construct comprehensive phase diagrams delineating regions characterized by extended topologically nontrivial states, critical localization, and coexisting topological and critical localization phases. The paper also addresses the dynamics of qubit excitations, elucidating distinct quantum state transfers resulting from the intricate interplay between topology and localization. Additionally, we propose a method for detecting diverse quantum phases utilizing existing experimental setups.

《反外国制裁法》第12条和《阻断办法》第9条初步搭建了我国反制裁追偿诉讼制度，但前者规定更加宽泛，赋予我国当事人针对根据外国歧视性限制措施作出的仲裁裁决提起反制裁追偿诉讼的权利，会与国际商事仲裁制度产生多方面冲突。为更好统筹发展与安全，应将反制裁追偿诉讼中司法对仲裁的介入控制在合理且必要的限度内，以在增强涉外法律斗争能力和支持商事仲裁制度营造良好涉外法治环境之间保持平衡。总体上，人民法院应审慎适用追偿诉讼条款，优先利用《纽约公约》公共政策保留和互惠原则阻断外国单边经济制裁的域外适用和相关仲裁裁决的效力；特定场景下，适用追偿诉讼条款作为兜底性的司法救济渠道。
