Simulating ion sputtered depth profiles in Auger electron spectroscopy
(University of the Free State, 2004-05)
Recent developments in advanced materials technology are mainly based on the progress in surface and interface science. These surface and interface properties of materials greatly affect and control the overall properties ...
The effect of nitrogen on the cosegregation of molybdenum in a Fe-3.5wt%Mo-N (100) single crystal
(University of the Free State, 2006)
In this study the cosegregation of molybdenum and nitrogen to the (100) plane of an iron single crystal was investigated. Ternary systems are considerably more complex than binary systems in that there are seven segregation ...
The segregation of indium from polycrystalline copper crystals
(University of the Free State, 2012-02)
In this study the surface segregation of In from a dilute Cu(In) alloy to the surface was investigated. The Cu(In) alloy was prepared by diffusion doping. A thin layer of In was deposited onto the backside of a polycrystalline ...
Experimental and computational study of S segregation in Fe
(University of the Free State, 2012-06)
A systematic study was conducted to investigate the diffusion and segregation of S in bcc Fe using (i) DFT modelling and (ii) the experimental techniques Auger Electron Spectroscopy (AES) and XRay diffraction (XRD). The ...
Segregation in a Cu bicrystal
(University of the Free State, 2010-11)
A literature study showed that the rate of segregation to a Cu(110) surface is higher than to a Cu(111) surface. The difference is mainly due to a change in the vacancy formation energy which determines the diffusion ...
