=================================================================================

In kinematic approximation, by introducing a phase shift (α) at a stacking fault, the TEM imaging intensity (|Ag|2) is given by,

       TEM Imaging of Stacking Faults -------------------- [1996a]
where,
          α -- (= 2πg·R) The phase shift at the stacking fault;
          R -- The displacement of the crystal below the stacking fault relative to that above it;
          s -- The deviation parameter;
          z -- The stacking fault depth.

Equation 1996a indicates that the visibility of the stacking fault is dependent on α, s, and z.
