摘要
One-dimensional (1D) nanoscale "crystalline-amorphous" carbon heterojunction is fabricated by post-treatment of an amorphous carbon nanofiber in a spark plasma sintering (SPS) system. It is proposed that the unique SPS process is responsible for the heterojunction formation. Studies of the electrical transport property show that the nanoscale heterojunction exhibits a typical rectification behavior. The heterojunctions may have broad potential applications in nanoelectronics and optoelectronics and the SPS technique could be a distinctive approach to construct 1D functional nanomaterials with high throughput.
