Semiconductor Electronics Materials Devices and Simple Circuits - Result Question 20
20. Which one of the following statement is FALSE?
[2010]
(a) Pure Si doped with trivalent impurities gives a p-type semiconductor
(b) Majority carriers in a n-type semiconductor are holes
(c) Minority carriers in a p-type semiconductor are electrons
(d) The resistance of intrinsic semiconductor decreases with increase of temperature
Show Answer
Answer:
Correct Answer: 20. (b)
Solution:
- (b) Majority carriers in an n-type semiconductor are electrons.
The current due to minority carriers in the junction diode is independent of the applied voltage. It only depends upon the temperature of the diode.
