A new strategy for atomic resolution compositional mapping at semiconductor interfaces is presented. Images can be interpreted directly to within 10% to give column-by-column compositional information with a sensitivity approaching Rutherford scattering cross sections. We apply the method to obtain the first atomic resolution images of interfacial ordering in ultrathin (Si{sub m}Ge{sub n}){sub p} superlattices and attribute the results to growth on (2 {times} 1) and (1 {times} 2) reconstructed surfaces. 13 refs., 7 figs.
