Abstract

Nitrogen-doped p-type ZnTe nanowires were successfully synthesized by a chemical vapor deposition method. Schottky junctions based on Au/ZnTe NW/In structure were constructed and their device performances were studied. ZnTe/In Schottky junction devices show excellent rectifying characteristics with rectification ratio up to 103 within ±5 V. Photoresponse analysis reveals that such devices were highly sensitive to varying optical signal with excellent stability, reproducibility and fast response speeds of 69/120 μs. These results demonstrate that ZnTe/In Schottky junction devices will promote the applications of ZnTe 1D nanostructures in electronic and optoelectronics.
