Contribution
It introduces a detailed analysis of fragmentation instabilities in nanoscale fractal islands, highlighting the role of geometric and deposition parameters in their evolution.
Findings
Fragmentation driven by arm length-to-width ratio.
Deposition conditions affect instability dynamics.
Relaxation to equilibrium shapes observed.
Abstract
Formation and evolution of fragmentation instabilities in fractal islands, obtained by deposition of silver clusters on graphite, are studied. The fragmentation dynamics and subsequent relaxation to the equilibrium shapes are controlled by the deposition conditions and cluster composition. Sharing common features with other materials' breakup phenomena, the fragmentation instability is governed by the length-to-width ratio of the fractal arms.
