Electrical Conductivity of a Semiconductor (σ = e(nμn + pμp))
jee-mainjee-advanced
σ = e(nμn + pμp)
What each symbol means
| Symbol | What it stands for |
|---|---|
| e | Elementary charge (C) |
| σ | Conductivity (S/m) |
| n, p | Electron and hole concentrations (m⁻³) |
| μ_n, μ_p | Electron and hole mobilities (m²/V·s) |
When to use this
Bulk drift conduction; both carrier types contribute additively. Mobilities are effective values at given T and doping.
