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:
“The message you give your children when you discipline with love is I care too much about you to let you misbehave. I care enough about you that Im willing to spend time and effort to help you learn what is appropriate. All children need the security and stability of food, shelter, love, and protection, but unless they also receive effective and appropriate discipline, they wont feel secure.”
—Stephanie Marston (20th century)
“The great mass of people ... will more easily fall victim to a big lie than to a small one.”
—Adolf Hitler (18891945)
“All the courses of my life do show
I am not in the roll of common men.”
—William Shakespeare (15641616)
