Hall Coefficient Calculator
Find the Hall coefficient from carrier density.
The Hall coefficient reveals the density and sign of charge carriers in a material.
The math behind it
R_H = 1 ÷ (n·q). A smaller carrier density gives a larger (easier to measure) Hall coefficient.
Worked example
Copper (n ≈ 8.5 × 10²⁸) → about 7.4 × 10⁻¹¹ m³/C.
FAQ
What does its sign tell you?
Negative for electron conduction, positive for hole conduction.
