Electrical Mobility Calculator

Find charge carrier mobility from drift velocity and field.

Drift velocity

Electric field (V/m)

Calculated Output

Mobility (m²/(V·s)) 0

Formula: μ = v_d ÷ E

Step-by-Step Breakdown

1. Values used:

2. Drift velocity = 0.0001

3. Electric field = 100 V/m

5. Mobility = Drift velocity / Electric field = 0.0001 / 100 = 0m²/(V·s)

Did this calculator solve your problem today?

The math behind it

μ = v_d ÷ E, the drift velocity per unit field. Higher mobility means faster, more conductive carriers.

v_d 0.1 mm/s in 100 V/m → 1 × 10⁻⁶ m²/(V·s).

Why does it matter in semiconductors?

Higher carrier mobility means faster transistors and better conductivity.
