1. The average electron-drift velocity in a semiconductor divided by the externally applied electric field.
2. A drift mobility of electrons in a semiconductor which consists of the electron velocity divided by the applied electric field.

1. The tendency of cells or compounds in a solution to move in an electric field toward an positive or negative electrode.
2. A characteristic of living cells in suspension (a dispersion of fine solid or liquid particles in a fluid) and biological compounds (proteins) in a solution to travel in an electric field to the positive or negative electrode, because of the charge on these substances.

The property of a barrier material that facilitates or impedes the movement of electrostatic charges internally or on the surface.

The ratio of the average drift velocity of an ion in a solution to the magnitude of the electric field causing the drift.
