The effective mass is used in transport calculations, such as transport of electrons under the influence of fields or carrier gradients, but also is used to calculate the density of states. These masses are related, but are not the same because the weighting of various directions and wavevectors are different. The density-of-states effective masses are tabulated below for a few cases.

Famous quotes containing the words effective, mass and/or common:

“... effective magic is transcendent nature ...”
—George Eliot [Mary Ann (or Marian)

“There are no fixtures in nature. The universe is fluid and volatile. Permanence is but a word of degrees. Our globe seen by God is a transparent law, not a mass of facts. The law dissolves the fact and holds it fluid.”
—Ralph Waldo Emerson (1803–1882)

“There is something antique, even, in his style of treating his subject, reminding us that Heroes and Demi-gods, Fates and Furies, still exist; the common man is nothing to him, but after death the hero is apotheosized and has a place in heaven, as in the religion of the Greeks.”
—Henry David Thoreau (1817–1862)
