Abstract

The epitaxial growth of an oriented crystalline substance from a melt (or solution) onto a substrate (Liquid Phase Epitaxy-LPE) is a process of high scientific and technological interest.1 The reproducibility, structural quality and purity of crystals obtained via LPE depend critically on a number of growth parameters such as the temperatures of the solid and melt, temperature gradients (in the direction of growth and laterally), the rates of heat dissipation and the compositions. The growth parameters, coupled with specific material characteristics such as thermal conductivities, latent heat, segregation and diffusion coefficients and crystalline anisotropics of material properties govern the kinetics and dynamics of the solidification process and the characteristics of the eventual product.

    Reduced units are used throughout the paper. The reduced time unit is (μσ2 /ε)1/2 where μ is mass, σ and ε are the Lennard-Jones (L-J) 6–12 parameters. For Argon σ = 3.4A, ε/k = 120°K and the time unit is 1.65 × 10-12 sec. Energy is in the unit of ε. The potential cutoff is 2.5 σ. In the figures, length is given in units of 7.94 σ.Google Scholar
