Patterns of influence of atomic network stretching on the electron-energy characteristics of thin films of perforated graphene

Abstract

This paper examines the effects of mechanical stretching on the electronic and energy characteristics of perforated graphene thin films. Observations of perforated graphene stretching suggest that its structure remains two-dimensional, but the distances and angles between carbon atoms change. This leads to deformation of the hexagonal cells and, consequently, the formation of new structures (triangles or other polygons) or structural rupture, even under uniform stretching. It was also found that perforated graphene exhibits higher tensile strength in the "armchair" direction than in the "zigzag" direction under stretching.
