Strain Engineering of 2D Materials: Issues and Opportunities at the Interface
Zhaohe Dai,Luqi Liu,Zhong Zhang +2 more
TL;DR: These advances highlight how the strain or strain-coupled applications of 2D materials rely on the interfacial properties, essentially shear and adhesion, and finally offer direct guidelines for deterministic design of mechanical strains into 2D material for ultrathin semiconductor applications.
Journal ArticleDOI
