Key Concepts

Electron-Hole Pair Generation

Electron-hole pair generation is a process in semiconductors where thermal energy promotes electrons from the valence band to the conduction band, creating a corresponding hole in the valence band. In intrinsic semiconductors, this process always produces electrons and holes in pairs, ensuring that the concentration of electrons is equal to the concentration of holes.

Intrinsic Semiconductors

Intrinsic semiconductors are pure semiconductor materials without any significant impurity doping. In these materials, the number of charge carriers is determined solely by the thermal generation process, resulting in equal numbers of electrons and holes. This intrinsic property is crucial for understanding the behavior and conductivity of the semiconductor under various temperature conditions.
