Passage

Comprehension:

Read the passage and answer the following five questions:

P-i-n photodiode contains a layer of intrinsic semi-conductor material sandwiched between p-and-n regions. The depletion layer is wholly contained within the i region. Thickness of the intrinsic region can be adjusted to produce device with optimum sensitivity and frequency response. P-i-n photodiode is most common type of depletion layer photodiode.

The other classes of photodiodes, avalanche photodiodes, are reverse-biased p-n junction diodes that are operated at voltages above the breakdown voltage. Current multiplication of electron-hole pairs generated by the incident electromagnetic radiation occurs due to avalanche process. The photo multiplication factor is defined as ratio of the multiplied photocurrent to the photocurrent at voltage below breakdown where no avalanche multiplication takes place.
