\[R_H=\frac{1}{nq}\]
Variables
RhHall coefficient (m^3/C)
ncharge carrier density (1/m^3)
qcharge of carrier (C)
Description
What is this formula?
This formula calculates the Hall coefficient of a conductive material from the charge carrier density and carrier charge.
When to use it
Use it when analyzing the Hall effect in conductors or semiconductors to determine carrier concentration and carrier type.
Example
Data:
n = 8.5e28 1/m^3
q = 1.602e-19 C
Formula:
Rh = 1/(n*q)
Substitution:
Rh = 1/((8.5e28)*(1.602e-19))
Result:
Rh = 7.34e-11 m^3/C
Applications
Semiconductor characterization, Hall effect measurements, carrier density analysis, magnetic sensors, and solid-state physics.
