Self-organized epitaxial growth of low-dimensional structures

Abstract

In heteroepitaxy, misfit strain can lead to a variety of fascinating phenomena during growth. These include self-organization of regular arrays of islands (&quantum dots&), of step bunches (which may serve as a template for growth of &quantum wires&), and of compositionally modulated layers (&quantum wells&). Some recent theoretical treatments of these phenomena are described. © 1998 Elsevier Science B.V. All rights reserved.
