Abstract
An outstanding goal in the study of crystal growth in the theoretical determination of optimal growth conditions for a specific surface morphology. We have developed a (1+1)-dimensional crystal-growth model which includes both a tunable substrate temperature and growth rate. A kinetic phase diagram, which reveals the dependence of the interface width dynamical exponent on temperature and growth rate, is constructed. The phase diagram contains two limiting phases described by different exponents. It is also demonstrated that the interface width can be minimized through a suitable choice of substrate temperature and deposition rate.
