Advanced Materials

The LEAP® Microscope's superior compositional imaging holds significant potential for addressing the many problems associated with the development and production of nano-materials such as:

  • Nanowires
  • Nanotubes
  • Fullerenes ("bucky balls")
  • Quantum dots

Microstructures in Nickel Superalloy

Superalloy Microstructure 		The atom probe microscope is well suited to materials characterization at the nano scale, making it very useful for nano-structure analysis in advanced materials research. Read More...
Quantum Wells

A reconstruction of 4 quantum wells in a GaN specimen. Only the indium (orange) atoms are displayed in the left image. Figures B and C shows isosurface plots of indium mole fraction for each quantum well.

Optoelectronic devices based on InxGa1-xN quantum well (QW) structures have been shown to emit bright light in the visible spectrum despite usually having a large density of threading dislocations in the GaN substrate which are thought to act as non-radiative recombination centers. Read More...
Analysis of an InAs Nanowire

InAS nanowire reconstruction 		The figure shows a 14x14x23 nm reconstruction of the tip region of an InAS nanowire grown via the vapor-liquid-solid (VLS) method using a gold catalyst. Read More...
