چکیده
The application of focused ion beam (FIB) machining in several technologies aimed at microstructure fabrication is presented. These emergent applications include the production of micromilling tools for machining of metals and the production of microsurgical tools. An example of the use of microsurgical manipulators in a circulatory system measurement is presented. The steps needed to transform the laboratory fabrication of these tools and manipulators into a routine FIB production process are discussed. The ion milling of threedimensional cavities by the exact solution of a mathematical model of the FIB deflection is demonstrated. A good agreement between the model calculation and the ion beam control has been obtained for parabolic and cosine cross-section features with planes of symmetry. q 1999 Elsevier Science Ltd.

The properties of transition metal oxides are related to the presence of elements with mixed valences. The spectroscopy analysis of the valence states is feasible experimentally, but a spatial mapping of valence states of transition metal elements is a challenge to existing microscopy techniques. In this paper, with the use of valence state information provided by the white lines and near-edge ...

A scanning transmission electron microscope (STEM) is used to examine the structural and chemical quality of the interface between thin films of YBa2Cu3O72d (YBCO) and BaF2. The STEM images indicate that it is possible to grow a uniform thin film of BaF2 that is relatively free of gross defects via a thermal evaporation method on top of a YBCO thin film. The diffraction contrast results also su...
