Abstract:

We have 1 established an electrodeposition procedure for silver with bright finish, which is associated with better electrical and physical properties than non-bright finish, 2 increased silver adhesion strength to gallium arsenide substrates using a titanium adhesion layer, and 3 characterized hardness and electrical conductivity of plated silver before and after rapid thermal annealing to find the optimum annealing conditions. We have also established a deposition protocol for silvercarboxylated carbon nanotube layer-by-layer composite films. We observed that the silver erosion during carboxylated carbon nanotube deposition leads to significant porosity within the composite films. We plan to explore amine-terminated carbon nanotubes in the near future to eliminate the porosity and study how different composite microstructures affect the mechanical and electrical properties of composite films.
