Electrical Mobility Calculator
Find charge carrier mobility from drift velocity and field.
Electrical mobility measures how quickly charge carriers drift in an electric field.
The math behind it
μ = v_d ÷ E, the drift velocity per unit field. Higher mobility means faster, more conductive carriers.
Worked example
v_d 0.1 mm/s in 100 V/m → 1 × 10⁻⁶ m²/(V·s).
FAQ
Why does it matter in semiconductors?
Higher carrier mobility means faster transistors and better conductivity.
