(a) High density of (100) poles in the center of the figure along the sample normal ( axis) direction. (b) Distribution of (001) poles along the equator along the sample transverse ( axis) direction.
Grain maps of tin stripes angle: (a) as-received sample and (b) after electromigration. The grey scale refers to the angle between the axis and the projection of (100) on plane.
Schematic diagram of a large angle grain boundary. The arrow indicates the direction of electron flow.
Sn line stressed with at . Grains indicated by arrows grew asymmetrically in the same direction as electron flow.
