摘要: Abstract We show by Kinetic Monte Carlo simulations that the leapfrog diffusion mechanism leads to a selective faceting and non-monotonic behavior of roughness during epitaxial growth missing-row (1 1 0) surfaces. At intermediate temperatures, (3 3 1) (1 1 1) nanofacets are formed in equal proportions, while at high temperatures surface presents almost only facets. An analytical formula for onset temperature is derived.
