摘要：
We demonstrated the variation of product morphology by varying the underlying surface characteristics, which were controlled by predeposition annealing. The surface roughness of the underlying In2O3 layer affected the resultant product morphology, indicating that rougher substrate favored the formation of one-dimensional (1D) structures. The obtained MgO nanowires were a single-crystal cubic structure. The PL measurement with a Gaussian fitting exhibited visible light emission bands centered at 2.26 eV and 2.86 eV.
