The large-area (quasi-)vdW epitaxy of layered 2D chalcogenides is consequently carefully being researched since these materials hold very promising properties for future nanoelectronic applications. The formation of defects such as stacking faults like 60o twins and consequently 60o grain boundaries is still of major concern for the defect-free epitaxial growth of 2D chalcogenides. Although growth strategies to overcome the occurrence of these defects are currently being considered, more fundamental understanding on the origin of these defects at the initial stages of the growth is highly essential. Therefore this work focuses on the understanding of 60o twin formation in (quasi-)vdW epitaxy of 2D chalcogenides relying on systematic molecular beam epitaxy (MBE) experiments supported by density functional theory (DFT) calc...
