Define diffusion length:
Sol. Diffusion length is defined as the distance, travelled by free carriers before recombining. It may also be defined as the average distance covered by an excess carrier during its life time is π. The mean time that a carrier exists between it, undergoes recombination is called mean life time. The mean life time and the diffusion length L are related to each other.
