The effective minority carrier lifetime in polycrystalline semiconductors is determined in terms of the grain size and the recombination velocity at the grain boundaries. The effect of the grain boundaries is to reduce the effective lifetime when the grain size is smaller than few diffusion lengths.
## Abstract A model of grain boundary structure is presented which is based on the concept of planar matching across the interface. This approach yields those displacements necessary to define the defect, population, and where possible, localisation of these displacements is seen to generate a vari
