title: Structure and Conductance of Aluminum Nanocontacts Studied by In Situ High-Resolution Transmission Electron Microscopy.
abstract: The structural dynamics and conductance of aluminum nanocontacts (NCs) during mechanical breaking was investigated in situ by high-resolution transmission electron microscopy. When the minimum cross-sectional width of the NCs was found to decrease to less than 1.3 nm at a bias voltage of 12.9 mV, a large strain was introduced in the minimum cross section region. The critical width of straining increased with bias voltage. Below the critical width, the current density started to decrease.
