comment Why do the drift and diffusion components cancel for each type of carrier if EHP generation plays such big role in p-n-junctions?
I see no mention of zero bias in the question. And even for zero bias photoexcited carriers generated inside p-n junction will give you non-zero total current (which means that components are not compensated). That's how photodiode works.

Your first sentence is nonsense. If drift and diffusion components cancel each other, the current through p-n junction is zero and diode has infinite resistivity. Which contradicts the facts. It seems that your question is incomplete: you mean no bias, or some other conditions?

comment Is all matter made of virtual particles?
It is much,much more complicated than stated in the article. So much that the main article line is completely wrong.

comment How creation of point defects in semiconductors is affected by strain?
I am interested in the regime when no dislocations appear in the system. And no, there are no dislocations in the system. At least, their number is negligible.

I'll take a look, but the titles make me think that not much about point defects is discussed there.
