Theoretical analyses have always resulted in nanomaterials' grain size probability distribution being of varied form: approximately either lognormal, Rayleigh, normal, Weibull, etc. The isotropic Hillert's model of grain growth which is more suitable for soap froth has been frequently used to establ
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.
