Abstract
The current paper examines the homo-epitaxial growth for two materials Ni and Fe via Kinetic Monte-Carlo (KMC) simulations based on the solid-on-solid model. We have investigated a qualitative and quantitative study for these materials. The stable surface is studied under various growth temperatures. We have extracted the critical exponents from the corresponding asymptotic behavior of the height-height correction function. Our results were compared to the available theoretical results and seem advantageous for a better understanding of the growth dynamics. We also discussed how the energy value of the next-nearest-neighbor (NNN) affects the scaling exponents and the roughness of the unstable surface morphology, due to the presence of an Ehrlich–Schwoebel (ES) barrier. We found that their effect becomes very clear in the case of Fe rather than Ni material.
期刊介绍:
The journal offers a common reference and publication source for workers engaged in research on the experimental and theoretical aspects of crystal growth and its applications, e.g. in devices. Experimental and theoretical contributions are published in the following fields: theory of nucleation and growth, molecular kinetics and transport phenomena, crystallization in viscous media such as polymers and glasses; crystal growth of metals, minerals, semiconductors, superconductors, magnetics, inorganic, organic and biological substances in bulk or as thin films; molecular beam epitaxy, chemical vapor deposition, growth of III-V and II-VI and other semiconductors; characterization of single crystals by physical and chemical methods; apparatus, instrumentation and techniques for crystal growth, and purification methods; multilayer heterostructures and their characterisation with an emphasis on crystal growth and epitaxial aspects of electronic materials. A special feature of the journal is the periodic inclusion of proceedings of symposia and conferences on relevant aspects of crystal growth.
