Self-Organizing Semiconductor Epitaxial Films by Turing Instability

Abstract
We describe for the first time diagrams of the surface topography domain in a strained InGaAs/AlGaAs system grown on GaAs (311)B/A surfaces during metalorganic-vapor-phase-epitaxial growth. The surface rearrangement process resulting in the stationary pattern formation of the various quasi-periodic nanostructures seems to belong to the class of a Turing-type self-organization phenomenon in non-linear dynamic systems. Experimental results might indicate the existence of a novel fourth growth mode due to Turing-type self-organization in addition to the three well-known epitaxial growth modes.
