Abstract (Leitet Herunterladen der Datei einDownload):

Monolithic integration of III-V compound semiconductor lasers in the telecom band on Si still remains challenging. Nanowire structure provides an alternative solution because of its high ability of lattice relaxation. We have developed gold-free CMOS-compatible growth process for InP/InAs quantum nanostructure nanowires with high controllability (structure and doping) and superior optical property. The nanowire exhibits lasing behavior in the telecom band at room temperature.
