Fractured surface from LaFeAs-OF sample imaged JPG Fractured surface from LaFeAs-OF sample imaged using a laser scanning confocal image (LSCM). A white light (LED source) image is used to color a higher resolution scanning laser generated image. The fracture image is used to reveal the existence of multiple phases as well as the grain size. The LSCM also provides volumetric data on the sample that is used in conjunction with electrical measurements made at the Applied Superconductivity Center and NHMFL. The Polycrystalline LaFeAsO0.89F0.11 samples were made by solid state synthesis at ORNL: Sefat, A. S. et al. Electron correlations in the superconductor LaFeAsO0.89F0.11 with low carrier density. Phys. Rev. B 77 174503 (2008).

Mist over Fe-Oxypnictide Landscape. Laser Scanning Confocal Microsopy provides us with the precise geometric and measurements we require in order to accurately compare sample properties. This low angle projection and fog were generated using Scandium 5 software from 3D data generated by an Olympus OLS3100 LSCM. The Ba(Fe0.9Co0.1)2As2 (Co-doped 122 phase) was produced by Jianyi Jiang and had a Tc of 23 K
