The electron microscopy of superconducting materials

Analytical microscopy of iron-based superconducting materials

Inhomogeneity and phase separation in unconventional superconducting materials is a topic of increasing interest, as the competition between phases with different types of ordering is thought to play an important role in the emergence of the high temperature superconducting state. A wide range of experimental techniques are available for investigating the crystallography of these complex materi...

Photo Electron Emission Microscopy of Polarity-patterned Materials Photo Electron Emission Microscopy of Polarity-patterned Materials

This study presents variable photon energy photo electron emission microscopy (PEEM) of polarity-patterned epitaxial GaN films, and ferroelectric LiNbO3 (LNO) single crystals and PbZrTiO3 (PZT) thin films. The photo electrons were excited with spontaneous emission from the tunable UV free electron laser (FEL) at Duke University. We report PEEM observation of polarity contrast and measurement of...

Electron Microscopy of Fowl Pox Virus

Examination of Lung Parenchyma by Electron Microscopy

In this paper many of the principal struc­ture of the Moral Lung were studied with the help of Electron Microscopy. Detailed descrip­tion was given of Granular Pneumocytes, Membranous Pneumocytes, Macrophages, and Alveolar Capillaries. A discussion followed on the form and function of Granular Pneumo­cytes.  Acknowledgements  I am grateful to the Reza Shah Pahlavi Foundation for its generou...

Scanning electron microscopy for materials characterization

Current materials are usually complex in chemistry, three-dimensional in form, and of rapidly diminishing microstructural scale. To characterize such materials the scanning electron microscope (SEM) now uses a wide range of operating conditions to target the desired sample volume, sophisticated modeling techniques to interpret the data. It also uses novel imaging modes to derive new types of in...
