Abstract
A pinch-off phenomenon is discovered in the evolution of 2D wormlike nanocl usters formed in homoepitaxial adlayers. This feature is shown to distingui sh mass transport via periphery diffusion from other mechanisms. Continuum modeling of such evolution accurately describes experimental observations, particularly if one incorporates the anisotropy in step-edge line tension.
