.023 x 10^22 atoms per cubic centimeter. What is its resistivity?
The resistivity of a semiconductor can be calculated using the formula:
ρ = 1/(q * μ * n)
where ρ is the resistivity, q is the charge of an electron (1.602 x 10^-19 C), μ is the electron mobility, and n is the electron concentration.
The electron mobility of a semiconductor depends on its material properties and can be found in tables. For this example, we will assume a mobility of 1400 cm^2/Vs for a silicon semiconductor.
Plugging in the values:
ρ = 1/(1.602 x 10^-19 C * 1400 cm^2/Vs * 6.023 x 10^22 atoms/cm^3)
ρ = 2.33 x 10^-3 Ω-cm
Therefore, the resistivity of the semiconductor is 2.33 x 10^-3 Ω-cm.

Here,there is a hole in n type insulator due to the surrounding atoms. And there is no presence of hole in other semi conductor.Simple❤
