We discuss the use of resonant photoemission in the study of rare earth/transition metal perovskites and perovskite-related structures. We illustrate its application to the assignment of the RE and TM valence band density of states in Nd 2 Ni 1− x

We have studied the oxidation of Mg(0 0 0 1) using electron stimulated desorption ion angular distributions, low energy electron diffraction (LEED) and scanning tunneling microscopy (STM). Two structures associated with the oxidation were observed by

The oxidation of Mg(0001) was studied using LEED (Low Energy Electron Diffraction) and ESDIAD (Electron Stimulated Desorption Ion Angular Distributions) with supplemental information from STM (Scanning Tunneling Microscopy). In agreement with previou

Fe films, oxidized on a Cu(001) substrate, have been found to form large, uniformly thick patches of oxide that dominate the mesoscopic surface structure producing large, atomically flat terraces. The oxide is found to grow in highly oriented chains,

The morphology of ultrathin Fe oxide films grown on Cu(001) was studied by STM and LEED. The oxide was grown in situ by high-temperature oxidation of Fe films deposited on a Cu(001) substrate at room temperature. The Fe films were observed to grow in

We find that the photoelectron angular distributions from the Fermi surface of a monolayer Ni film on Cu are identical to those from thick Ni films and single-crystal Ni(001), and agree well with theoretical predictions for bulk Ni. This bulklike beh

We have studied the Fermi surface of Cu using an ellipsoidal-mirror analyzer which gives two-dimensional images of photoelectron intensity versus emission angle. From these images, we have obtained the full Fermi surface of Cu in three-dimensional k

A soft X-ray plane grating monochromator installed at Louisiana State University's Center for Advanced Microstructures and Devices has been characterized and the first experimental results obtained. The monochromator is a modified SX-700 design which

When clean, vacuum-fractured surfaces of BaTiO 3 are analyzed using ultraviolet and x-ray photoelectron spectroscopy (UPS and XPS), more than one set of barium core levels is observed. Sputtering the surface with ions removes lower-binding-energy int

We present valence and core-level photoemission measurements from vacuum-fractured, single-crystal barium titanate. These results resolve contradictory measurements in the literature which have employed other methods of sample surface preparation. Th
