Majority and Minority Charge Carriers in Semiconductors

WebThe majority carriers don't matter because they are passive: they are considered to just "sit there" in the lattice waiting for the minority carrier. Why minority carriers have a lifetime is that the lattice is not fully doped. Only some small fraction of the atoms have a hole, or surplus electron.

WebRemember that the minority carrier lifetime is the hole lifetime in n type semiconductors and the electron lifetime in p type semiconductors. In n type conductors you have lots of electrons from donor gap states but only a few holes in the valence band. So the lifetime is the time for a hole to recombine with one of the large excess of electrons. WebOn the p side, the holes constitute the dominant carriers and so are called majority carriers. A few thermally generated electrons will also exist in the p side; these are termed …
