Direct measurements of island growth and step-edge barriers in colloidal epitaxy.
Epitaxial growth, a bottom-up self-assembly process for creating surface nano- and microstructures, has been extensively studied in the context of atoms. This process, however, is also a promising route to self-assembly of nanometer- and micrometer-scale particles into microstructures that have numerous technological applications. To determine whether atomic epitaxial growth laws are applicable...
متن کاملNucleation, growth, and kinetic roughening of metal(100) homoepitaxial thin films
A unified analysis is presented of submonolayer nucleation and growth of two-dimensional islands and the subsequent transition to multilayer growth during metal-on-unreconstructed metal(100) homoepitaxy. First, we review and augment recent developments in submonolayer nucleation theory for general critical size i (above which islands are effectively stable against dissociation). We discuss choi...
متن کاملLayered Growth of Lattice-Mismatched GaxIn1 xP on GaP Substrates by Liquid Phase Epitaxy
We report layered growth of GaxIn1 xP on GaP substrates using single-step liquid phase epitaxy (LPE) with a Sn-based melt when the lattice mismatch is greater than 0.4 % (x< 0.95). Compositional control was observed by (1) varying the cooling rate and (2) changing the melt-back temperature at the beginning of the growth. Possible growth mechanisms are proposed to explain the principles of both ...
متن کاملLarge scale surface structure formed during GaAs (001) homoepitaxy
Atomic force microscopy studies have been performed on GaAs (001) homoepitaxy Rlrns grown by molecular beam epitaxy. Multilayered features are seen to evolve when the growth conditions favor island nucleation. As the epilayer thickness is increased these features grow in all dimensions but the angle of inclination remains approximately constant at 1”. The mounding does not occur on surfaces gro...
متن کاملFour Lectures on the Physics of Crystal Growth
Several aspects of the theory of epitaxial crystal growth from atomic or molecular beams are developed from the perspective of statistical physics. Lectures are devoted to the rate equation theory of two-dimensional nucleation and its limitations; the growth of multilayer wedding cakes in the presence of strong step edge barriers; the continuum theory of mound coarsening; and growth-induced ste...
