Electromigration at 100 K

Electromigration is the thermally assisted motion of metal lattice ions driven by the strong momentum transfer of charge carries under the applied electrical field.
The movie corresponds to the in-situ TEM recording of grain growth and the electromigration process at low temperature (~100K) in a thin Pt bridge under passing of electrical current.
