Calculate the resistivity of an n-type semiconductor from the following data:density of conduction electrons `=8xx10^13cm^(-3)`,density of holes `=5xx10^12cm^(-3),`mobility of conduction electron `=2.3xx10^(4)cm^(2)V_(-1)s_(-1)`and mobility of holes`=100cm^(2)V_(-1)s_(-1 ).`

Explanation

To calculate the resistivity of an n-type semiconductor, we will follow these steps:

### Step 1: Identify the given values
We have the following data:
- Density of conduction electrons, \( n_e = 8 \times 10^{13} \, \text{cm}^{-3} \)
- Density of holes, \( n_h = 5 \times 10^{12} \, \text{cm}^{-3} \)
- Mobility of conduction electrons, \( \mu_e = 2.3 \times 10^{4} \, \text{cm}^2 \, \text{V}^{-1} \, \text{s}^{-1} \)
- Mobility of holes, \( \mu_h = 100 \, \text{cm}^2 \, \text{V}^{-1} \, \text{s}^{-1} \)
