              Carrier 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. Its value directly reflects the quality and purity of the semiconductor material, as well as the potential performance of devices. Below is a detailed explanation: 1.
