Anisotropic strain effects in small-twist-angle graphene on graphite
Anisotropic strain effects in small-twist-angle graphene on graphite
The direct experimental probing of locally varying lattice parameters and anisotropic lattice deformations in atomic multilayers is extremely challenging. Here, we develop a combined numerical and graphical method for the analysis of irregular moir\'e superstructures measured by scanning tunneling microscopy (STM) on a small-twist-angle ($\ensuremath{\sim}0.{6}^{\ensuremath{\circ}}$) graphene on highly oriented pyrolytic …
