If \(n_e\) and \(n_h\) are electron and hole concentrations in an extrinsic semiconductor and \(n_i\) is electron concentrations in an intrinsic semiconductor, then
- A \(\left(\frac{n_e}{n_h}\right)=n_i\)
- B \(\left(n_e+n_h\right)=n_i\)
- C \(\left(n_e-n_h\right)=n_i^2\)
- D \(n_e n_h=n_i^2\)
Answer & Solution
Correct Answer
(D) \(n_e n_h=n_i^2\)
Step-by-step Solution
Detailed explanation
\(n_e\) and \(n_h\) are electron and hole concentrations in an extrinsic semiconductor and \(n_i\) is electron concentration in an intrinsic semiconductor, then \[ n_e n_h=n_i^2 \]
