Read shockley equation

WebAug 15, 2007 · The stored energy has been calculated from the microstructural observations using the Read–Shockley equation. This equation takes into account both the dislocation line energy and the dislocation core energy. In another formulation, the stored energy can be equated, instead, to the elastic line energy of the each dislocation line, given as 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.
