摘要：
We report on the fabrication of GaAs and InGaAs hexagonal nanowires surrounded by {110} vertical facets on GaAs (111)B and InP (111)B substrates using selective area (SA) MOVPE growth. The substrate for SA-growth was partially covered with thin SiO2 and circular mask opening with diameter d(0) of 50-200 nm was defined. After SA-MOVPE, GaAs or InGaAs nanowires with the typical diameter d ranging from 50 nm to 200 nm and height 2 mu m to 9 mu m was formed vertically on the substrates, depending on the growth conditions and the pattern geometry. Possible growth mechanism is also discussed.
