Abstract
Devices with nanosized particles deposited on shaped surface geometries include a substrate with an active material of nanosized particles deposited on a surface of the substrate. The active material has an edge formed at a position determined with a shaped geometry of the surface.
Claims20
A device comprising:
- a substrate;
- and
- a plurality of droplets of carrier liquid, the carrier liquid comprising an active material of nanosized particles, wherein the droplets of carrier liquid are deposited on a surface of said substrate, and wherein the droplets of carrier liquid are deposited on a number of planes above a plurality of trenches defined in said substrate and comprise an edge formed at a position determined by a transition from the number of planes to the trenches,
- wherein the droplets of carrier liquid are deposited on the surface of the substrate to form an energy pathway comprising overlapping regions of active material relative to active material of a neighboring droplet of carrier liquid,
- wherein an offset between the trenches and a pinned edge of the active material is determined at least partially by the size of the nanosized particles within the active material.

A system with nanosized particles deposited on shaped surface geometries, comprising:
- a substrate with an active material of nanosized particles deposited on a surface of said substrate, said active material comprising an outer edge formed at a position determined with a shaped geometry of said surface, the shaped geometry comprising a plurality of trenches defined in said substrate outside of and bounding the outer edge of the active material,
- wherein a first set of said plurality of trenches are formed perpendicular to and cross a second set of said plurality of trenches such that a plane is surrounded on four sides by the first and second sets of trenches in said surface of said substrate,
- wherein a plurality of droplets of carrier liquid are deposited on the surface of the substrate to form an energy pathway comprising overlapping regions of active material relative to active material of a neighboring drop of carrier liquid, and
- wherein an offset between the trenches and a pinned edge of the active material is determined at least partially by the size of the nanosized particles within the active material.
