Magnetic and Transport Studies on Electron-Doped CeFeAsO1-xFxSuperconductor

Electron transport in pure and doped hematite.

Hematite (α-Fe(2)O(3)) is a promising candidate for photoelectrochemical splitting of water. However, its intrinsically poor conductivity is a major drawback. Doping hematite to make it either p-type or n-type enhances its measured conductivity. We use quantum mechanics to understand how titanium, zirconium, silicon, or germanium n-type doping affects the electron transport mechanism in hematit...

Studies on the Terminal Electron Transport System

The present communication is devoted to the description of the isolation, properties, and composition of a particulate unit which we shall refer to as the succinic dehydrogenase complex (SDC). The working hypothesis underlying this and subsequent communications in this series is that SDC is a unit of enzymatic action in the same sense as any well defined soluble enzyme. Since the discovery of s...

Magnetic interactions and electron transport in hole - doped manganite - superconducting cuprate heterostructures

Studies of structures, transport and magnetic properties of doped novel three-dimensional perovskite compounds

Magnetic, orbital and charge ordering in the electron-doped manganites

The three dimensional perovskite manganites R1−xAxMnO3 in the range of holedoping x > 0.5 are studied in detail using a double exchange model with degenerate eg orbitals including intraand inter-orbital correlations and near-neighbour Coulomb repulsion. We show that such a model captures the observed phase diagram and orbital-ordering in the intermediate to large band-width regime. It is argued...
