The Σ3 (GB) can be described as a twist boundary characterized by a layered structure. In this GB, each grain's top and bottom layers are derived from bulk silicon with a relative twist angle of 60°between them. We have implemented the bicrystal model of GB. Subsequently, layers from each grain are systematically stacked atop one another, a process facilitated by our custom Python script. One notable advantage of this approach is the precise control it provides over the number of layers within each grain, allowing for tailored investigations.
