InAs nanostructures on InAlAs=InP(0 0 1) have been fabricated using Stranski-Krastanov growth mode. Depending on growth conditions, a full coverage of the InAlAs surface by either InAs strings of elongated dots or isolated dots can be achieved. Giant intraband absorptions are observed at mid-infrare
