摘要：

Bi/Bi2S3 heteronanowires were in situ synthesized via an electrochemical synthesis. Pure Bi nanowires were first formed in the pores of AAM by electrodeposition. With increasing the reaction temperature, Bi2S3 were formed through reaction between Bi and S. The synthesized Bi2S3 microhedgehogs composed of nanoneedles were found standing on the surface of AAM after overgrowth. The possible growth process was proposed briefly. Nonlinear electrical transport was observed in the Bi/Bi2S3 system. The obtained Bi/Bi2S3 heterostructure may find applications in optical, electrical and gas sensor devices. (c) 2007 Elsevier B.V.
