We report on the transition from two-dimensional to one-dimensional (1D) behavior observed in submonolayer deposition on a tubular substrate. Using kinetic Monte Carlo simulations we show that the island density increases when the tube diameter decreases, approaching the 1D behavior. This increase is confirmed by experiments of FePt nanoparticle deposition on carbon nanotubes. Kinetic Monte Carlo simulations also indicate that the consequences of confinement sharply disappear when the perimeter of the tube is slightly larger than the distance between islands.
