Atomic resolution studies of oxide superlattices and ultrathin films
… to develop a number of epitaxial oxide systems grown on single crystal oxide substrates that display a wide variety of novel interfacial functionality, such as enhanced ferromagnetic ordering, increased charge carrier density, increased optical absorption, etc, at interfaces. The magnitude …

Superconductivity in oxygen doped iron telluride by molecular beam epitaxy
… the sample with AFM, XRD, transport, and STEM-EELS, and we found that interfacial strain is not an essential ingredient of superconductivity in this particular case. We investigated the doping conditions for two candidate oxygen doping modes: substitution and interstitial. We found that …

Mapping plasmon excitations in gold nanostructures using electron energy loss spectroscopy
… our samples and emulate the experimental system in HAMR we devised and carried out an intricate sample preparation using a focused ion beam. We were able to resolve the plasmonics of the encapsulated nanostructures and compared the results to samples with no encapsulating …

Microscopic Study of Structure, Chemical Composition and Local Conductivity of La2/3Sr1/3MnO3 Films
… scanning transmission electron microscopy (STEM), and electron energy loss spectroscopy (EELS). Substantial deviations in Sr doping concentrations from its bulk value are observed at both the interface and surface. Deviation at the interface is due mainly to single unit cell intermixing, …

Deformation mechanisms in a polycrystalline Ni-based superalloy
… TEM (HR-TEM), energy-dispersive X-ray (STEM-EDX) and electron energy loss (STEM-EELS) spectroscopy to study SFs generated during the alloy’s heat treatment, which have not been described as such before. These extended SFs were found in significant densities on up to four slip systems in …

Magnesium nanoplasmonics: synthesis, characterisation, and applications
At the nanoscale, light-matter interactions differ markedly from bulk behavior. In metal nanoparticles, resonant oscillations of conduction-band electrons driven by light lead to localised surface plasmon resonances (LSPRs). Au and Ag are widely studied metals capable of sustaining LSPRs, but there …
