Self-organization of wire-like InAs nanostructures on InP

The initial InAs growth on InP(1 0 0) during molecular beam epitaxy has bee n investigated. The as-grown islands were shaped like nanowires and formed dense arrays over the entire surface in the 3-6 monolayer InAs deposition r ange. The wires were oriented along the [(1) over bar 1 0] direction. Trans mission electron microscopy images confirm that the wires are coherently gr own on the substrates. Our results suggest that the coherent wire-shaped is land formation may be a possible method to fabricate self-organized InAs na nowires. (C) 1999 Elsevier Science B.V. All rights reserved.
