SUMMARY

The product of n0 (electron concentration) and po (hole concentration) in semiconductors is always a constant for a given material due to the principle of charge neutrality. For intrinsic semiconductors, n0 equals po, leading to the equation n0 * po = ni^2, where ni represents the intrinsic carrier concentration. In extrinsic semiconductors, the carrier concentration is influenced by temperature, but the relationship between n0 and po remains governed by the same principles, ensuring that both electrons and holes contribute to the overall carrier concentration.

Why is the product of n0 and po always a constant for a given semiconductor?
I mean i can agree for an intrinsic semiconductor that n0=po therefore n0*p0=ni^2.
Also for an extrinsic semiconductor the carrier concentration "ni" is a function of temperature agreed! But for that concentration what do we take into account? electrons or holes or both?

Also i know for an intrinsic semiconductor n0=p0=ni.
