Herding cats: managing gold atoms on common transparent dielectrics [Invited]

Simple methods to control the self-organization of gold atoms on commonly employed transparent dielectrics are presented. On one hand, surface diffusion of gold atoms can be suppressed to a sufficient degree as to realize ultra-thin (as low as approximately 5 nm) void-free semi-transparent conductin...

Summary:Simple methods to control the self-organization of gold atoms on commonly employed transparent dielectrics are presented. On one hand, surface diffusion of gold atoms can be suppressed to a sufficient degree as to realize ultra-thin (as low as approximately 5 nm) void-free semi-transparent conducting gold films over macroscopic areas while, on the other hand, their high surface mobility can be harnessed to fabricate large-area substrates compatible with cell culturing and imaging, having widely tunable field-enhancement properties for surface-enhanced Raman scattering.
