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)

“Detachment is the prerogative of an elite; and as the dandy is the nineteenth century’s surrogate for the aristocrat in matters of culture, so Camp is the modern dandyism. Camp is the answer to the problem: how to be a dandy in the age of mass culture.”
—Susan Sontag (b. 1933)

“The most common error made in matters of appearance is the belief that one should disdain the superficial and let the true beauty of one’s soul shine through. If there are places on your body where this is a possibility, you are not attractive—you are leaking.”
—Fran Lebowitz (b. 1951)
