We have used high resolution transmission electron microscopy and mechanically controllable break junction technique to study metal NW structure and electrical transport properties. In the last stages just before rupture, gold and platinum nanowires are crystalline and defect‐free. In particular, gold NWs assume merely three kinds of atomic arrangements, which were correlated to observed conductance behaviors.
