Abstract
The present invention relates to a method for fabricating an array of nanoparticle clusters, in which a thermally transformable organic liquid crystal film having a periodic array of micro-sized dimple-like defect structures spontaneously transformed by thermal sublimation of liquid crystal molecules is used as a template, and nanoparticles form self-assembled clusters having a uniform size with respect to the defect structures, thereby achieving a periodic array of nanoparticle clusters.
Claims17
A method for fabricating a liquid crystal film, comprising thermally annealing a sublimable liquid crystal supermolecule on a substrate.
A method for fabricating an array of nanoparticle clusters comprising the steps of:
- (a) thermally annealing a sublimable liquid crystal supermolecule on a substrate, and cooling the thermally annealed supermolecule to induce periodic micro-defect structures, thereby forming a liquid crystal film on the substrate;
- and
- (b) allowing nanoparticles to form self-assembled clusters with the defect structures as their center by using the formed liquid crystal film as a template.
