sci.Hall-effect-carrier-density Calculator
Calculates Hall voltage V_H = IB/(nqt) and carrier concentration n from Hall effect measurements in a semiconductor or conductor. Hall effect identifies carrier type (electrons vs holes) and concentration — typical n-doped silicon at 10¹⁶ cm⁻³ gives V_H ≈ 0.1 mV in a 0.1 T field.
Inputs
I A
Rate of charge flow (A). I = V/R. Above ~100 mA through the body can be lethal. Fuses protect against overcurrent.
B T
Reference formula or conversion factor shown for context.
T M
Perpendicular measurement through the material. For insulation: thicker is better. For beams: directly affects bending resistance.
V H V
Electric potential difference (V). Drives current through a circuit. Household: 120 V (US) or 230 V (EU/UK).
Results
carrier concentration n (m⁻³)
The proportional relationship between two quantities.
Hall coefficient R_H (m³/C)
Sample size or count used in the calculation.
carrier concentration (cm⁻³)
The proportional relationship between two quantities.
n = IB/(e·V_H·t)
Sample size or count used in the calculation.
material type
The classification or type assigned based on the inputs.
