Abstract: The present invention relates generally to dendritic metal structures and devices including them. The present invention also relates particularly to methods for making dendritic metal structures without the use of solid electrolyte materials. In one aspect, a method for constructing a dendritic metal structure includes providing a substrate having a surface and a cathode disposed on the surface; providing an anode comprising a metal; and disposing a liquid on the surface of the substrate, such that the liquid is in electrical contact with the anode and the cathode; and then applying a bias voltage across the cathode and the anode sufficient to grow the dendritic metal structure extending from the cathode. The methods described herein can be used to grow dendritic metal electrodes, which can be useful in devices such as LEDs, touchscreens, solar cells and photodetectors.

Abstract: The present invention relates generally to plasmonic structures, methods for making them, and devices including them. In one aspect, a plasmonic structure includes a plurality of metal particles disposed on a substrate; and one or more metal structures electrically coupled to and disposed on a surface of each of the plurality of metal particles. The metal structures have a structure that is different than the structure of the metal particles. The metal structures can be grown, for example, by electrodeposition on the metal particles. Growth of such metal structures can tune the response of the plasmonic structure.
