Abstract
A method is presented for use in fabrication of metal islands on an oxide substrate. The method comprises: depositing a selected metal on the oxide substrate by evaporation of said selected metal; and annealing a film of the selected metal on said substrate at temperatures including an annealing temperature being less than 50° C. lower than a glass transition temperature, thereby forming the metal islands partially embedded in said substrate.

A method of fabrication of metal islands on an oxide substrate, the method comprising:
- depositing a selected metal on the oxide substrate by evaporation of said selected metal;
- and
- annealing a film of the selected metal on said substrate at temperatures including an annealing temperature being less than 50° C. lower than a glass transition temperature of said oxide substrate, thereby forming the metal islands partially embedded in said substrate.
A method of fabrication of a metal island film on glass, the method comprising
- depositing a selected metal on the glass by evaporation of said selected metal;
- and
- annealing a film of the selected metal on glass in presence of oxygen, said annealing being carried out at temperatures and for a period of time selected to produce substantially elongated islands partially embedded into said glass.
A structure comprising a plurality of metal islands on a glass substrate, said islands having a generally elongated geometry and being partially thermally embedded into said glass substrate.
A structure comprising a plurality of metal islands partially embedded into a glass substrate, a majority of said islands being embedded into depressions with a rim higher than 0.5 nm.
A structure comprising a plurality of metal islands partially embedded into a glass substrate, a majority of in-plane shapes of said islands having at least one crystallographic angle.
A structure comprising a glass substrate and a plurality of closed-loop glass nano-sized rims on said substrate, major axis of a majority of said rims being between 5 and 400 nm and heights of a majority of said rims being higher than 0.5 nm.
