Abstract:

Metals were evaporated under vacuum and the metal atoms solvated by excess organic solvents at low temperature. Upon warming stable colloidal metal particles were formed by controlled metal atom clustering. The particles were stabilized toward flocculation by solvation and electrostatic effects. Upon solvent removal the colloidal particles grew to form thin films that were metallic in appearance, bu showed higher resistivities than pure metallic films. Gold, palladium, and especially indium are discussed. Keywords Indium, palladium, thin films, colloidal metal particles, free atoms, solvated, indium oxide films, clustering, electrophoresis, living colloids, non-aqueous solutions.
