Abstract

<jats:title>Abstract</jats:title> <jats:p>Crystalline Co nanoparticles with unique faceted structures are synthesized on the sapphire substrate by annealing a sputtered Co film in H2 atmosphere. The high-temperature sputtering stimulates the epitaxial growth of the Co film, leading to the formation of ordered Co nanoparticles upon H2 annealing. The crystal structure of the Co nanoparticles is discussed.</jats:p>
