Abstract:
1. A process for producing sub-micron sized asymmetric structures, comprising: depositing a self-assembled monolayer onto a substrate, wherein an available surface of the self-assembled monolayer has an affinity for binding to a nanocrystal surface; contacting the available surface with a colloidal solution of nanocrystals to form a nanocrystal layer on the monolayer, wherein the nanocrystals are selected from the group consisting of Group II-VI, Group II-V, Group III-VI, Group III-V, Group I-III-VI, Group II-IV-VI, and Group II-IV-V compounds; depositing a protective polymer layer, the protective polymer layer covering a first portion of the nanocrystals, leaving a second portion of the nanocrystals exposed; and performing a functionalizing reaction on the second portion of the nanocrystals, to form asymmetric functionalized nanocrystals, wherein the functionalizing comprises
