a Restoring force as a function of normalized shear S(x)/|b|, where |b| is the length of Burger vector, 5.5774 Å; b normalized shear distribution S(x)/|b| and dislocation density ρ(x) as a function of the distance x from the dislocation core. It should be noted that ρ(x) refers to the density of infinitesimal dislocations in Eq. (1). The unfilled circles in this figure denote the normalized shear distribution measured from the HRTEM image as shown in (d); c variation of the misfit energy W as a function of the position u of the dislocation core for the [011](0\(\bar{1}1\)) edge dislocation, the minimum misfit energy Wmin is 362.12E−11 J/m; d high-resolution transmission electron microscopy (HRTEM) image containing two partial 〈011〉{011}-type dislocations from the [100] perspective. The Burgers circle yields a Burgers vector \(\frac{1}{2}\)[011] of the left partial dislocation. The HRTEM image near another partial dislocation is not clear, so the area, encircled by the rectangle, overlaps its Fourier-filtered image. The right partial dislocation is marked by the dotted line circle. Source data are provided as a Source Data file.
