Effective Mass For Some Common Semiconductors
Group | Material | Electron me | Hole mh |
---|---|---|---|
IV | Si (300K) | 1.08 | 0.56 |
Ge | 0.55 | 0.37 | |
III-V | GaAs | 0.067 | 0.45 |
InSb | 0.013 | 0.6 | |
II-VI | ZnO | 0.29 | 1.21 |
ZnSe | 0.17 | 1.44 |
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:
“More! is as effective a revolutionary slogan as was ever invented by doctrinaires of discontent. The American, who cannot learn to want what he has, is a permanent revolutionary.”
—Eric Hoffer (19021983)
“No atomic physicist has to worry, people will always want to kill other people on a mass scale. Sure, hes got the fridge full of sausages and spring water.”
—William Burroughs (b. 1914)
“There ought to be an absolute dictatorship ... a dictatorship of painters ... a dictatorship of one painter ... to suppress all those who have betrayed us, to suppress the cheaters, to suppress the tricks, to suppress mannerisms, to suppress charms, to suppress history, to suppress a heap of other things. But common sense always gets away with it. Above all, lets have a revolution against that!”
—Pablo Picasso (18811973)
