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:
“Recent studies that have investigated maternal satisfaction have found this to be a better prediction of mother-child interaction than work status alone. More important for the overall quality of interaction with their children than simply whether the mother works or not, these studies suggest, is how satisfied the mother is with her role as worker or homemaker. Satisfied women are consistently more warm, involved, playful, stimulating and effective with their children than unsatisfied women.”
—Alison Clarke-Stewart (20th century)
“Too much traffic with a quotation book begets a conviction of ignorance in a sensitive reader. Not only is there a mass of quotable stuff he never quotes, but an even vaster realm of which he has never heard.”
—Robertson Davies (b. 1913)
“It is quite a common and vulgar thing among humans to understand, foresee, know and predict the troubles of others. But oh what a rare thing it is to predict, know, foresee and understand one’s own troubles.”
—François Rabelais (1494–1553)
