Based on the systematic studies of the growth temperature, deposition rate, and annealing effects, the control of Co nanoparticle density, size, and alignment is demonstrated to be feasible on a nanostructured template Al2 O3 NiAl (100). At 140-170 K, a slow deposition rate (0.027 MLmin) promises both the linear alignment and the high particle density. 1.5 ML Co nanoparticle assembly sustains the density of ∼260 104 nm2 even after 800-1090 K annealing. This study also indicates the possibilities of the controlled growth for nanoparticles of different materials.
