Debye Length

In plasmas and electrolytes the Debye length (also called Debye radius), named after the Dutch physicist and physical chemist Peter Debye, is the scale over which mobile charge carriers (e.g. electrons) screen out electric fields. In other words, the Debye length is the distance over which significant charge separation can occur. A Debye sphere is a volume whose radius is the Debye length, in which there is a sphere of influence, and outside of which charges are screened. The notion of Debye length plays an important role in plasma physics, electrolytes and colloids (DLVO theory).

Famous quotes containing the word length:

    We praise a man who feels angry on the right grounds and against the right persons and also in the right manner at the right moment and for the right length of time.
    Aristotle (384–322 B.C.)
