What is the relationship between electron density (n) and hole density (p) in an intrinsic semiconductor?
What is the relationship between electron density (n) and hole density (p) in an intrinsic semiconductor?
- n < p
- The relationship cannot be determined
- n = p (correct)
- n > p
What is the intrinsic carrier density (ni) in an intrinsic semiconductor?
What is the intrinsic carrier density (ni) in an intrinsic semiconductor?
- $ni = rac{ ext{Energy gap}}{2} imes rac{1}{{ ext{Boltzmann constant} imes ext{Temperature}}}$ (correct)
- $ni = rac{ ext{Energy gap}}{2} imes rac{1}{{ ext{Boltzmann constant} + ext{Temperature}}}$
- $ni = rac{ ext{Energy gap}}{2} imes rac{1}{{ ext{Boltzmann constant} - ext{Temperature}}}$
- $ni = rac{ ext{Energy gap}}{2} imes rac{1}{{ ext{Boltzmann constant} imes ext{Temperature}^2}}$
What effect does temperature have on the intrinsic carrier density (ni) in an intrinsic semiconductor?
What effect does temperature have on the intrinsic carrier density (ni) in an intrinsic semiconductor?
