Abstract

Rough surfaces generated by a wide range of different processes can be described quite well in terms of self-affine fractal geometry. Here ballistic deposition models are used to illustrate some of the fractal characteristics that are common to many rough surfaces. The models also show how computer simulations and theoretical approaches have been used in a complementary manner to obtain a better understanding of the structure and growth of random rough surfaces. Some results obtained for ballistic deposition at oblique incidence and for spatially correlated ballistic deposition represent some of the recent advances made in these directions.
