Patent ID: 8415086

Claim:
A method for achieving low energy states of functionally coupled islands of a functional material, said functionally coupled island being places within a chirality kagome spin ice structure comprising a honeycomb lattice ring structure, each ring structure having six axis declined by an angle of about 60° one axis to the other, comprising the steps of; a) providing a silicon substrate; b) coating a photoresist material, such as a polymethyl acrylate resist, on said silicon substrate; c) providing an electron beam writer or a photon beam writer; d) exposing said coated substrate to an electron beam from said electron beam writer or to a photon beam of said photon beam writer, whereby said exposing forms geometric configuration being a kagome ring component having at least one ring structure; thereby breaking monomer chains of the polymethyl acrylate resist in said exposed region; e) removing the broken monomer chains in order to achieve void islands and positioning in a variety of said void islands more than one functionally coupled island, each of the functionally coupled islands being oriented along one of the six axis of the honeycomb lattice ring structure of said kagome spin ice component, wherein the functionally coupled islands are substantially identical in length but differ in width; f) said functionally coupled island structures providing a mechanism in which chirality is controlled according to the physical property of the functional material in the functionally coupled islands.
