The conductance image between two probes of scanning‐tunneling‐microscopy (STM) is calculated in a zigzag carbon nanotube within a tight‐binding model and a realistic model for STM probes. A Kekulé‐type pattern usually appears due to interference of states at K and K' points. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
