Growth model with disaggregation of islands having an odd number of particles.
A simple model of deposition of particles and growth of point islands in a two-dimensional substrate is introduced and studied. The detachment of particles from islands with an odd number of particles can occur with a probability P. The power-law scalings of the island, monomer, and odd island densities are analytically obtained and verified by Monte Carlo simulations. The universality class of the model depends on P, and the island density exponent chi changes from chi=1/3 (for P=0 ) to chi=0 (for P>0 ).
