Glow Discharge Depth Profiling a Powerful Analytical Technique in Surface Engineering (TECHNICAL NOTE)
A variety of analytical techniques have been developed and employed to characterize the surfaces, subsurfaces and interfaces of surface engineering systems. They provide important information for quality control, process optimization and further development. Since the mid 1980's, glow discharge spectrometry (GDS) has emerged as an important and versatile technique for rapid depth profiling anal...
متن کاملSoftware for Modelling Positron-Beam Depth-Profiling Data
The fitting program VEPFIT has been extended with applications running under the Microsoft Windows environment facilitating the input and output of the VEPFIT fitting module. We have exploited the Microsoft-Windowsm graphical users interface by making use of dialog windows, scrollbars, command buttons etc. The user communicates with the program simply by clicking and dragging with the mouse poi...
متن کاملDepth Layers from Occlusions
We present a method to extract relative depth information from an uncalibrated monocular video sequence. Our method detects occlusions caused by an object moving in a static scene to infer relative depth relationships between scene parts. Our approach does not rely on any strong assumptions about the object or the scene to aid in this segmentation into layers. In general, the problem of buildin...
متن کاملDepth-Profiling of Surface-Segregated Composition Spread Alloy Films
It is common for the components in a homogeneous metallic alloy to separate at its surface. This phenomenon is known as surface segregation. For example, under certain conditions, the surface layer of atoms in a Cu85Pd15 is pure copper, while the second layer of atoms is 50% copper. The bulk retains its 85/15 composition. A depth-profile characterizes the surface segregation by describing the a...
متن کاملMolecular Depth Profiling.
Bombardment of molecular solids with polyatomic projectiles allows interrogation of the sample with reduced chemical damage accumulation. Hence, it is now common to perform depth profiling experiments using a variety of substrates in a fashion similar to that reported for inorganic materials in use for many decades. The possibility for chemical processes, however, creates a number of fundamenta...
