摘要
The growth of ultrathin films of titanium (less than or equal to 2 monolayers) on the (0001) plane of sapphire at room temperature was investigated by in-situ Auger electron spectroscopy. Quantification of experimental measurements showed that the interface between titanium and sapphire was composed of a suboxide of titanium and partially reduced aluminium oxide. interface formation starred with the appearance of a Ti2O3-type phase, which led to pure titanium with increasing film thickness.
