qelementary charge (C)
phole concentration (1/m³)
mu_phole mobility (m²/(V·s))
Description
What is this formula?
The Hole Conductivity formula calculates the electrical conductivity contribution produced by holes in a semiconductor material.
When to use it
Use this formula when studying p-type semiconductors, carrier transport, semiconductor device physics, or integrated electronic circuits.
Example
A p-type semiconductor has:
q = 1.6×10^-19 C
p = 5×10^21 1/m³
mu_p = 0.05 m²/(V·s)
Formula:
sigma_p = q p mu_p
Substitution:
sigma_p = (1.6×10^-19)(5×10^21)(0.05)
Result:
sigma_p = 40 S/m
The hole conductivity is 40 S/m.
Applications
Semiconductor analysis, transistor physics, integrated circuits, carrier transport studies, and electronic materials engineering.
