Looking for a postdoctoral researcher with excellent experience with transport measurement of critical current density, Jc (field, temperature, angle) using a PPMS system and chemical etching of bridges on REBCO films. Should be fully familiar with flux-pinning in superconductors and analysis of superconducting properties. Preferably, will also have experience in growth of REBCO films using pulsed laser deposition.  Looking for another postdoctoral researcher with excellent experience with high-resolution electron microscopy including TEM, STEM, EELS. Particular experience in characterization of REBCO-type superconductors preferred. Should also have excellent experience doing structural characterization using X-ray diffraction and full crystallographic texture analysis. Research
