Description: This work is essentially an update of previous compilations of information on the diffusivity of elements in semiconductor-grade silicon. It subsumes the data contained in B.L.Sharma’s monograph on ‘Diffusion in Semiconductors‘ (Trans Tech Publications, 1970), plus the data contained in Diffusion and Defect Data (Diffusion in Silicon) Volume 45 (1986), Defect and Diffusion Forum (Diffusion in Silicon - 10 years of Research) Volumes 153-155 (1998), Defect and Diffusion Forum (Diffusion in Silicon - a Seven-Year Retrospective) Volume 241 (2005) and the latest data from recent Semiconductor Retrospectives: Defect and Diffusion Forum, Volumes 245-246, Volumes 261-262, Volume 272 and Volume 282. In addition, the resultant 400 items of data were analysed in the hope of finding some unifying correlation. It was indeed found that all of the points (each the average of many independent measurements) seemed to fall on a number of distinct straight lines passing through the origin of a plot of activation energy versus atomic radius. However, it remained unclear how these correlations could be explained.

Description: Current water-treatment technologies require considerable energy consumption. Thus, closely linked to the problem of water shortage is the impending energy crisis. Therefore, intensive research is being aimed at developing water purification processes that are based upon using renewable energy, such as solar energy, rather than energy generated using fossil fuels. There has been an accumulation of reports on the development of photocatalysts, which enable water purification using solar energy as the only driving force. Such photocatalysts, based upon oxide semiconductors, permit the conversion of solar energy into the chemical energy that is required for the oxidation of toxic organic compounds in water. The most promising photocatalyst is titanium dioxide, TiO2, and its solid solutions. The research on TiO2 photocatalysis is multidisciplinary, and progress in this area requires the application of concepts of catalysis and photocatalysis as well as concepts of solid-state chemistry.

Description: Diffusion is always central to many scientific and technological fields. From the recognition of Fick´s laws, up to the present day, there have been very important diffusion-based contributions made to fields such as biology, nanosciences, chemistry, physics, etc. Volume is indexed by Thomson Reuters CPCI-S (WoS)
Description: It is well-known, even at the most elementary level of scientific knowledge, that free surfaces have properties which make them differ from the underlying bulk material. In the case of liquids, it is common knowledge - even among laymen - that the liquid surface acts as though it were a distinct skin-like material. At a slightly more advanced level, it is known that the liquid surface will seek to minimize its total surface energy by minimizing its surface area; thereby affecting its local vapor-pressure and adsorption behavior. In the case of solids too, it has long been known that different crystallographic surfaces have different surface energies and that this can decide which surfaces ‘survive’ during crystal growth, and govern how solids - especially small particles - respond to prolonged annealing. However, although it was perhaps theoretically ‘obvious’, it is only relatively recently (since the 1950s) that it has come to be realized that solid surfaces will seek to minimize their total surface energy not only by minimizing their area, but also by changing their local surface structure. This process has come to be known as surface reconstruction. Study of this phenomenon has exploded in interest in recent years, partly because of the ever-increasing sophistication of the experimental techniques available for examining surfaces in the required detail, and partly because of the importance of the phenomenon in such fields as catalysis and layered (epitaxial) construction of semiconducting devices.
