Single-phase self-assembled crystalline cuprous oxide nanoclusters in the size range of 10-50 nm were grown on the SrTiO 3(100) substrate. The formation of pure epitaxially stabilized Cu 2O nanodots was confirmed at the growth parameters which were different in comparison with the Cu-O bulk phase diagram. For pure Cu 2O, morphology consisted of isolated small square/rectangular clusters with flat tops and oriented mostly along the same <100> direction, indicating possible phaselike separation for the cuprous and cupric oxides. Observed changes in the nanocluster composition were found to correlate with differences in cluster morphologies.
