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. https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.121.266101

Pseudomagnetic Fields in a Locally Strained Graphene Drumhead

Recent experiments reveal that a scanning tunneling microscopy (STM) probe tip can generate a highly localized strain field in a graphene drumhead, which in turn leads to pseudomagnetic fields in the graphene that can spatially confine graphene charge carriers in a way similar to a lithographically defined quantum dot (QD). While these experimental findings are intriguing, their further implementation in nanoelectronic devices hinges upon the knowledge of key underpinning parameters, which still remain elusive.
