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:
“Gestures ..., in love, are incomparably more attractive, effective and valuable than words.”
—François Rabelais (14941553)
“It is a mass language only in the same sense that its baseball slang is born of baseball players. That is, it is a language which is being molded by writers to do delicate things and yet be within the grasp of superficially educated people. It is not a natural growth, much as its proletarian writers would like to think so. But compared with it at its best, English has reached the Alexandrian stage of formalism and decay.”
—Raymond Chandler (18881959)
“When a man says that he is Jesus or Napoleon, or that the Martians are after him, or claims something else that seems outrageous to common sense, he is labeled psychotic and locked up in a madhouse. Freedom of speech is only for normal people.”
—Thomas Szasz (b. 1920)
