We introduce a solid-on-solid lattice model for growth with conditional evaporation. A measure of finite size effects is obtained by observing the time invariance of distribution of local height fluctuations. The model parameters are chosen so that the change in the distribution in time is minimum. On a one-dimensional substrate the results obtained from(More)

Mounding instability in a conserved growth from vapor is analyzed within the framework of adatom kinetics on the growing surface. The analysis shows that depending on the local structure of the surface, kinetics of adatoms may vary, leading to disjoint regions in the sense of a continuum description. This is manifested particularly under the conditions of(More)

A (2+1)-dimensional stochastic growth model is proposed in order to understand various experimental observations at low temperature growth. The model includes step attached adatom hopping in the upward direction to provide a source of additional particle current. The flexibility obtained due to additional current control allows one to express most of the(More)

A method based on the kinetics of adatoms on a growing surface under epitaxial growth at low temperature in (1+1) dimensions is proposed to obtain a closed form of the local growth equation. It can be generalized to any growth problem where surface morphology is governed by adatom diffusion. The method can be easily extended to higher dimensions. The(More)
