This paper addresses the state of art nano science and technology regarding next generation high density microelectronics and photonics packaging applications, including carbon nanotubes (CNTs) for electrical/thermal devices, nano lead-free alloy, molecular wires for electrical interconnects, etc.
A large amount of carbon nanotubes with uniform diameter were produced from catalytic decomposition of C2H2 or CH4 over perovskite oxide LaCoO3 catalyst precersor. The result of XRD measurement indicated that after reduction of LaCoO3 at 700 ○C cobalt existed chiefly as Co0 particles supported and separated by La2O3. La2O3 can prevent Co0 from agglomeration. The size of Co0 nanoparticles determined...
A large amount of more graphitic carbon nanotubes with a narrow size distribution was produced from catalytic decomposition of CH4 over pre-reduced LaNiO3, La4Ni3O10, La3Ni2O7 and La2NiO4. The structure and component of fresh and reduced LaNiO3, La4Ni3O10, La3Ni2O7 and La2NiO4 were determined by X-ray diffraction (XRD). The carbon nanotubes obtained were characterized by means of transmission electron...
