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:

    “Gestures ..., in love, are incomparably more attractive, effective and valuable than words.”
    —François Rabelais (1494–1553)

    “As a rule, all heroism is due to a lack of reflection, and thus it is necessary to maintain a mass of imbeciles. If they once understand themselves the ruling men will be lost.”
    —Ernest Renan (1823–1892)

    “What climbs the stair?
    Nothing that common women ponder on
    If you are worth my hope! Neither Content
    Nor satisfied Conscience, but that great family
    Some ancient famous authors misrepresent,
    The Proud Furies each with her torch on high.”
    —William Butler Yeats (1865–1939)
