Tunable PhoXonic Band Gap Materials from Self-Assembly of Block Copolymers and Colloidal Nanocrystals (NBIT Phase II)

摘要

This collaborative Korea-USA proposal aims to design and fabricate tunable phoxonic band gap materials by self-assembly of block copolymer and/or colloidal crystals, characterize the resultant structures and finally measure and model/simulate their novel properties defined by their interaction with photons and phonons. Concerning this, we seek to develop methods and understanding to create both periodically structured materials (Bragg gap materials) and non-periodically structured materials (resonance gap materials). For that, self-assembly of block copolymers is chosen for creating a model system of tunable Bragg gap material, and self-assembly of colloidal crystals is for tunable resonance gap materials. This proposal brings a complete set of activities together to invent and exploit new periodic/non-periodic materials based on self-assembly systems.
