【Abstract】 Since the discovery of carbon nanotube in 1991, many efforts have been made to fabricate nanojunction as building blocks for nanoelectronics devices, such as intermolecular metal-semiconductor nanojunction and nanotube crossed nanojunction. However, the controlled growth of this sort of nanojunctions is still in its infancy. In the present work, multi-intramolecular junctions array of single-walled carbon nanotubes (SWCNTs) has been fabricated by temperature oscillated chemical vapor deposition (CVD). Micro-resonance Raman spectroscopy was used to detect the metallic-metallic, metallic-semiconductor and semiconductor-semiconductor SWCNTs junctions.更多还原
