Abstract
Expressions are given for the fields of the elastic displacements and the elastic component of the excitation error for a composition-modulated crystal. Calculated and experimental dilatational contrast transmission electron-microscope images are compared for a spontaneously modulated GaAsP/GaAs composition. It is demonstrated that the experimental images correspond to continuous variations in the composition which are possible in a “ synergistic” model of nonequilibrium order.
