Which of the following is true in case of a forward biased p-n junction diode?
Answer: a Explanation: The diode is forward biased, positive is connected to p & vice-versa, as such batter provides EMF to drive electrons from n-region to p-region.
Answer: a
See lessExplanation: The diode is forward biased, positive is connected to p & vice-versa, as
such batter provides EMF to drive electrons from n-region to p-region.
Which of the following is true in case of an unbiased p-n junction diode?
Answer: d Explanation: A potential difference is established across the junctions due to recombination of holes & electrons. This growing filed (barrier potential) stops the further diffusion.
Answer: d
See lessExplanation: A potential difference is established across the junctions due to
recombination of holes & electrons. This growing filed (barrier potential) stops the further
diffusion.
When a physical contact between a p-region & n-region is established which of the following is most likely to take place?
Answer: c Explanation: When p & n region come together diffusion takes places & a depletion region is established with opposite charges on both the sides of the junction
Answer: c
See lessExplanation: When p & n region come together diffusion takes places & a depletion
region is established with opposite charges on both the sides of the junction
Lets assume that the doping density in the p-region is 10-9 cm-3 & in the n-region is 10-17cm-3 , as such the p-n junction so formed would be termed as a
Answer: b Explanation: Doping density is greater in the p-region compared to the n-region.
Answer: b
See lessExplanation: Doping density is greater in the p-region compared to the n-region.

A p-type semiconductor material is doped with ____________ impurities whereas a n-type semiconductor material is doped with __________ impurities
Answer: a Explanation: Donor impurities denote an electron to the n-type material making it a electron majority carrier & vice-versa.
Answer: a
See lessExplanation: Donor impurities denote an electron to the n-type material making it a
electron majority carrier & vice-versa.
