Structural characterization of long ZnSe nanowires

ZnSe nanowires have been synthesized by vapor transport in an Ar atmosphere. The synthesized ZnSe nanowires have a thickness of 20 to 120 nm and a length of tens of micrometers. The nanowires are single crystals with a cubic zinc-blende structure growing along the 111] direction. The as-synthesized nanowires display rich Raman modes and one photoluminescence band peaking at around 450 nm. PACS 78.67.Bf; 81.07.Bc; 61.46.+w
