Fig. 5: The STEM images and illustration of strain field in ReS2.
From: Mechanical origin of martensite-like structures in two-dimensional ReS2
a–c The STEM annular dark field (ADF) images showing the typical twinning domain boundary structures stemming from free edges, the diamond chain directions (b direction in Fig. 6) are highlighted, scale bars =1 nm. d The tensile tractions on ReS2 flake exerted by the engaged substrate. e The sketch map of the tensile strain level, decreasing from the center to flake edges. f The mechanical schematic of tensile strain resulted interfacial sliding and traction forces in equilibrium. g The diagram illustration traction and strain level associated with the location in the sample flakes.
