Using the Siemen's Elmiskop I, the morphology of alpha-SnO grown under reduced pressure on thin polycrystalline tin films was studied. The effects of varying the exposure time, oxygen pressure and reaction temperature were investigated. Epitaxial (200) oriented tin films were grown by the condensation of tin onto a cooled rocksalt substrate. The films were oxidised under reduced pressure and the orientation of alpha-SnO with respect to the tin substrate was determined. Two orientation relationships were found: Sn [200] //SnO [111] and Sn [200] //SnO [110] Oxidation of the epitaxial films inside the electron microscope at a temperature below the melting point of alpha-Sn resulted in the formation of SnO2. The effect of water vapour on the structure and morphology of the oxide was also studied.
