The surface chemistry of tin(IV) oxide: Defects, doping and conductivity.
|Abstract||A review is given of the application of contemporary UHV surface science techniques to the study of the surface chemistry of tin(IV) oxide, SnO . Topics of particular interest include the nature of electronic states associated with oxygen vacancies at SnO surfaces; changes in electronic structure that may be brought about by doping (especially with Sb); and the relationship between bulk doping levels and surface dopant concentration. Interest foc ... [truncated at 450 characters in length]|
The late Palaeozoic relations between Gondwana and Laurussia
|Abstract||Reconstructions based on biogeography, palaeomagnetism and facies distributions indicate that, in later Palaeozoic time, there were no wide oceans separating the major continents. During the Silurian and Early Devonian time, many oceans became narrower so that only the less mobile animals and plants remained distinct. There were several continental collisions: the Tornquist Sea (between Baltica and Avalonia) closed in Late Ordovician time, the Ia ... [truncated at 450 characters in length]|
