摘要：

Based on density functional theory (DFT) predictions and scanning tunneling microscopy (STM) measurements we report the possibility of using the Cu(111) surface for growth of molybdenum sulfide nanowires (Mo6S6). Strong substrate interactions coupled with small lattice mismatch lead to epitaxial growth of the nanowires parallel to a set of substrate high symmetry directions. We observe a propensity for creation of aligned and equally spaced arrays of nanowires and use OFT to elucidate interaction strength both in the absence and presence of the substrate.
