Various annealing conditions (environment, temperature, and duration) are applied to study the nanoscale Kirkendall effect of copper (Cu) nanowire (NW) arrays on a Si substrate. The results show that an appropriate amount of oxygen supply is crucial for uniform transformation from Cu NWs (average diameter ∼50 nm) into Cu oxide nanotube arrays. An annealing(More)
In this study, we evaluate the application of copper nanoparticles as a low temperature bonded interconnection. The copper nanoparticles have an organic passivation layer which stabilizes them, preventing spontaneous particle fusion and growth at ambient temperatures, as well as avoiding oxidation before its usage. Thermogravimetric analysis and(More)
