We report the growth of needle-like high density quaternary ZnCdSeTe nanowires on oxidized Si(100) substrate using vapor-liquid-solid mechanism by molecular beam epitaxy with an Au-based nanocatalyst. It was found that average length and average diameter of the nanowires were 1.3 μm and 91 nm, respectively. It was also found that the as-grown ZnCdSeTe nanowires exhibit mixture of cubic zinc-blende and hexagonal wurtzite structures. Energy depersive results indicate that composition ratio of our nanowire should be Zn 0.87Cd 0.13Se 0.98Te 0.02, which agrees excellently with the designated composition ratio of Zn 0.87Cd 0.13Se 0.98Te 0.02.
