Mechanics at the interfaces of 2D materials

Dear iMechanica researchers,

I'd like to share an opinion paper that was written by Rui Huang, Kenneth Liechti, Nanshu Lu, and I for Current Opinion in Solid State & Materials Science. The aim is to discuss the mechanics research on 2D material interfaces in terms of recent developments and appeared challenges and opportunitiesHere is the link; Below, I also attached a copy of the manuscript and pasted the Abstract.

Bending of Multilayer van der Waals Materials

Dear colleagues, I'd like to share our recent work on blister testing of multilayer 2D materials that gives a direct measurement of Young's modulus and bending rigidity of a multilayer (~10-70 layers). Materials involved include graphene, MoS2, and hBN.

Strain Engineering of 2D Materials: Issues and Opportunities at the Interface

In this progress report, we reviewed recent advances in strategies for applying mechanical strain into 2D materials and recent state‐of‐the‐art characterizations of interface mechanics for 2D material–substrate systems.

Interface-Governed Deformation of Nanobubbles and Nanotents Formed by Two-Dimensional Materials

In this paper, we experimentally characterize a simple and unified power law for the profiles of a variety of nanobubbles and nanotents formed by 2D materials such as graphene and MoS2 layers.
