Abstract
Restricted solid-on-solid (RSOS) models with finite-distance hoppings are studied. A randomly dropped particle is allowed to hop to find the nearest site satisfying the RSOS condition within a finite hopping distance . If the particle can find such a site within the distance , then the growth is permitted at that site. If the particle cannot find the site within the distance , the particle is abandoned and the new particle is dropped. It is found that in the substrate dimensions and 2 the universality of such models crosses over from the Kadar - Parisi - Zhang (KPZ) class to the conserved-KPZ class at finite . The tilt-dependent growth velocity and the surface current are also studied to understand the crossover physically.
