Buried interfaces and surfaces play an essential role in the function of many materials for energy, environmental, and biological applications. An understanding of the physics and ultimate the ability to engineer materials with specific properties is aided by an atomic level understanding of the composition and morphology of interfaces. Atom probe tomography (APT) is a 3-dimensional compositional mapping technique based on the field evaporation of individual atoms from the tip of a needle-shaped specimen. At the Environmental Molecular Sciences Laboratory (EMSL), we are pushing the limits of APT analysis to study a wide variety of energy and environmental materials. We will present several examples that exemplify the breadth of materials which include semiconductor nanowires for high performance solar cell and transistors, geologic minerals used for atmospheric carbon sequestration, and glass materials for the vitrification of controlled waste.
