abstract = {Employing the focal-series reconstruction technique in
high-resolution transmission electron microscopy, we
obtained true atomic resolution images of interfacial
disorder within cation and anion sublattices across
interfaces in an InGaSb/InAs heterostructure. This enabled
independent quantitative mapping of changes in the In-Ga and
As-Sb contents across interfacial regions similar to 0.6 nm
in width. A comparison of the cation and anion sublattice
images revealed that intermixing at the InGaSb-on-InAs
interface is confined to the In-Ga sublattice. Also, atomic
scale roughness within the As-Sb sublattice of the
InAs-on-InGaSb interface was discerned. This approach is
general, permitting atomic-scale compositional analysis of
heterointerfaces with two species per sublattice. (c) 2006
