Drift velocity - Wikipedia, the free encyclopedia
The drift velocity is the average velocity that a particle, such as an electron, attains due to an electric field. In general, an electron will rattle around in a conductor at the Fermi velocity ran...

A microscopic view suggests that this proportionality comes from the fact that an applied electric field superimposes a small drift velocity on the free electrons in a metal.

Since electric charge is quantized in discrete multiples of the electron charge, it is instructive to look at electric current as the movement of multiple microscopic charge carriers with a drift velocity in a conductor.

The current in a wire can be expressed as function of the number of charge carriers/volume, the magnitude of the charge carriers, the drift velocity of the charge carriers, and the cross-sectional are of the wire,

Remind them that this is the drift velocity of the electrons inside the metal and is much lower than the actual individual velocities of electrons. They have thermal kinetic energy and it is useful to think of a gas of electrons with large random velocities whose nominal centre of mass drifts slowly along the metal tube.

For the charge carriers in a metal, the applied field superimposes a net drift velocity vd onto the random motion already there. ... If you turn on the field and watch the purple ball (which represents a typical electron) for a while, you should notice a net drift to the right. The field must therefore point to the...

In a conventional MOSFET, carriers are confined in a direction normal to the channel, and free to move in two dimensions. It is, however, now with Nanotubes possible to make structures that confine carriers in two dimensions, so that they are free to move only in one direction. ...
