Lifetime is a key parameter in semiconductor physics, used to describe the average time that non-equilibrium carriers (electrons or holes) survive in a material before recombination.

Basic Definition Carriers:Conductive particles in semiconductors, including electrons (negative charge) and holes (positive charge). When excited by light, electricity, or heat, electrons transition from the valence band to the conduction band, generating electron-hole pairs (i.e., non-equilibrium carriers).
