Abstract

The first photoelectron spectromicroscopy experiments at the new 1.3 GeV ultrabright X-ray source of SRRC have produced interesting results concerning chemical and topographic features in three types of systems: neuron networks grown on metal substrates, cleaved surfaces of high-quality single crystals of Bi2Ca2SrCu2Ox (BCSCO) and Au-covered GaSe. In the case of BCSCO, a general tendency to chemical homogeneity - extremely important for sophisticated spectroscopic applications - sharply conflict with occasional evidence of chemical-contrast features related to inhomogeneties in the Sr content. No chemical inhomogeneity was observed for the GaSe-Au case, in contrast to the lateral variations both in composition and in band bending previously found at submonolayer coverage.

Topography

Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the land forms and features themselves, or a description or depiction in maps. Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief, but also natural, artificial, and cultural features such as roads, land boundaries, and buildings.

Topographic map

In modern mapping, a topographic map or topographic sheet is a type of map characterized by large-scale detail and quantitative representation of relief features, usually using contour lines (connecting points of equal elevation), but historically using a variety of methods. Traditional definitions require a topographic map to show both natural and artificial features. A topographic survey is typically based upon a systematic observation and published as a map series, made up of two or more map sheets that combine to form the whole map.

Terrain

Terrain or relief (also topographical relief) involves the vertical and horizontal dimensions of land surface. The term bathymetry is used to describe underwater relief, while hypsometry studies terrain relative to sea level. The Latin word terra (the root of terrain) means "earth." In physical geography, terrain is the lay of the land. This is usually expressed in terms of the elevation, slope, and orientation of terrain features. Terrain affects surface water flow and distribution.
