Fig. 6.1 a STM/S morphology and energy states discriminates the chain-end Au atoms from that
in the interior of the monotomic chain [20]. b Coherent electron diffraction and MD derived Au
skin bond contraction in a 3.5 nm crystal (inset) [22]. STM/S (c) line scans (inset in d) of an Au
nanowire of different thickness and d the respective dI/dV spectrum. Results show the width effect
on the polarization of the valence DOS [21]. DFT derived polarization of the e size-resolved valence
DOS and f shell-resolved LDOS of an Au 75 cluster (inset denotes the layer number). Reprinted
