X-ray Photoelectron Spectroscopy Graphics Not Contained Overview This document is a comprehensive analysis on X-ray Photoelectron Spectroscopy (XPS), also a coating characterization technique. The first question that probably comes from your mind is, what exactly is surface characterization? Well, surface characterization is a process which enables us to understand every thing about the outside in attention. By means of this method, we know the kind of atoms present in the outside, the concentrations of these atoms, the specific locations of the electrons in the surface, the bond lengths and lengths of these molecules onto the surfaceand also the power of their bonding to the surface, and ultimately the effect that the surface bond would have on surface reactivity. Fundamentally, upon characterization, you will know the surface such as the back of your hand. The next question that might be asked would be, why do we want all this info about a surface? The answer to this question is a lot more universal and more general than you'd anticipate. All this information on a surface comes in handy once you're working with or analyzing a specific surface. This method may examine a surface as it's obtained and we can use the info, or you also could use it to compare after the surface has undergone certain therapy. Some examples of the В'remedy' are cutting, scratching, fracturing, Ultra High Vacuum (UHV), ion beam etching, exposure to heat, exposure to reactive pollutants or remedies, exposure to ion beam implant, and exposure to UV light among several others. The В'therapies' serve functions like vulnerability to mass chemistry (UHV), cleansing surface pollution (ion beam etching), and research of fluctuations.
