| the eigenfunction of the wave equation for a periodic potential is the product of a plane wave and the potential that has the periodicity of the crystal | bloch's theorem | 25%
|
| empty state in valence band due to excitation of an electron into the conduction band | hole | 25%
|
| a vector that describes the translational periodicity of a lattice | lattice vector | 25%
|
| region about a lattice point that is closer to that lattice point than any other | Wigner seitz cell | 25%
|
| ability of a charge carrier to move through a material in response to an electric field | carrier mobility | 0%
|
| electrons and holes recombine with each other resulting in no net charge carriers | depletion region | 0%
|
| majority carrier diffuse into minority region and recombine with majority carriers | diffusion current | 0%
|
| thermally generated minority carriers drift into the majority region, swept by built in e field | drift current | 0%
|
| in a filled band as many electrons move to the left as to the right | insulator | 0%
|
| total relaxation times is dependent on different sources (defects, impurities and phonons) | Matthiessen rule | 0%
|
| incomplete band filling creates a Fermi surface, electric field shifts Fermi surface so not as many electrons are moving to the left as the right | metal | 0%
|

|
| distance between fermi level and vacuum level | work function | 0%
