Abstract
The conserved Sine-Gordon equation with nonconserved shot noise is use d to model homoepitaxial crystal growth. With increasing coverage the renormalized pinning potential changes from strong to weak. This is in terpreted as a transition from layer-by-layer to rough growth. The ass ociated length and time scales are identified, and found to agree with recent scaling arguments. A heuristically postulated nonlinear term d el(2)(del h)(2) is created under renormalization.
