How do you find the resistivity of a semiconductor?
We know that resistivity is a multiplicative inverse of conductivity. Then resistivity ρ=1σ=1. 294=3.401Ω/cm=0.03401Ω/m. Note: Conductivity of a semiconductor is caused due to holes and conduction electrons present in it.

What is the resistivity ρ of silicon doped with 1017cm 3 of arsenic?
0.084 Ω-cm
(a) What is the resistivity (ρ) of silicon doped with 1017cm-3 of arsenic? Solution: (a) Using the N-type curve in the previous figure, we find that ρ = 0.084 Ω-cm.
What is resistivity equation?
Resistivity, commonly symbolized by the Greek letter rho, ρ, is quantitatively equal to the resistance R of a specimen such as a wire, multiplied by its cross-sectional area A, and divided by its length l; ρ = RA/l. Thus, in the metre-kilogram-second system, the unit of resistivity is ohm-metre.
