Webergy formula of Read and Shockley [2] was obtained based on the dislocation structure of low angle tilt boundaries in a simple cubic lattice that cancels the long-range elastic elds. Vitek [8] modi ed the grain boundary energy formula by including the interaction energy of intersecting dislocations in the dislocation structure of twist boundaries. Webconcentrations. In this work, the simplified Shockley-Read-Hall model is compared with a more general solution of the continuity equations that takes account of carrier trapping. This comparison leads to an expression for the upper limit on the recombination centre density for which the simplified Shockley-Read-Hall model remains accurate.
