This image by Robert Ulfig, CAMECA, won the  contest for the cover of Electronic Device Failure Analysis August 2012 issue. It features the 3D mapping of an Indium rich quantum wells shorted by a V-defect with Mg at the core. The  analysis depth displayed is approximately 160nm. For  clarity, only a fraction of the atoms are displayed.Pale Green: Ga and N atoms - Dark Green: Mg atoms - Blue: Isoconcentration surfaces of the In QWs where In > 0.25 at%. 2) Iron-based Superalloy Three-dimensional views of primary, secondary, and tertiary phases ,from near micron to sub nanometer scale, that provide strength an            d high temperature creep resistance in Iron-based Superalloys.

3) Arsenic ring Cottrell Atmospheres The concentrated Arsenic decorates defect structures formed from the ion implantation and subsequent anneal. Here, individual As atoms are represented by small spheres. For a proxigram 3D concentration contour analysis of this data see this page. Thompson, K., P. L. Flaitz, et al. (2007).
