| 31. | Under stimulation of light the electrons may free themselves from the trap and get into the conduction band.
|
| 32. | Suppose the conduction band of semiconductor 2 is closer to the vacuum level than that of semiconductor 1.
|
| 33. | Free electrons are in the conduction band of energy levels, while holes are in the valence energy band.
|
| 34. | The wide band element is doped with donor atoms; thus it has excess electrons in its conduction band.
|
| 35. | The ionizing radiation produces electron-hole pairs : Electrons are in the conduction band and holes in the valence band.
|
| 36. | The Fermi energy is below the conduction band causing the state density to be asymmetric around the Fermi energy.
|
| 37. | Above-bandgap light is used throughout the experiment to ensure that there are lots of electrons in the conduction band.
|
| 38. | The electrons that have been excited to the conduction band may become entrapped in the electron or hole traps.
|
| 39. | The empty row is analogous to the conduction band, and the person walking out is analogous to a free electron.
|
| 40. | Luminescence in a semiconductor results when an electron in the conduction band recombines with a hole in the valence band.
