中文摘要： 基于同一衬底上两种或两种以上有序纳米结构阵列的光、电、磁等特异性能，本项目拟通过两端链段A和C含不同功能基团的线型ABC三嵌段共聚物的自组装和相转变调控，构筑含两种功能性位点的周期性纳米图案；研究两种功能性位点对金属、金属氧化物纳米粒子的识别性能与作用机制；以该双功能周期性纳米图案为模板，结合功能性位点的识别性能，控制金属、金属氧化物纳米粒子吸附或键合在相应的纳米相位点；进而通过氧离子束蚀刻法或两步煅烧法去除嵌段共聚物模板，原位转移金属纳米粒子、金属氧化物纳米线于单晶硅衬底上，从而实现在同一衬底上制备两种位置、尺寸、取向均可控的金属/金属氧化物有序纳米阵列的目的。项目可为光电/半导体、光电/磁等多功能纳米器件的研究提供新思路。

英文摘要： Based on the special optical, electronic or magnetic properties of ordered nanostructure arrays with two or more kinds of nanoparticles/nanowires on one substrate, this proposed program focuses on self-assemble nanopatterns and mechanism of phase transition of linear ABC triblock copolymers with different functional groups in the two-end blocks of A and C to fabricate periodic nanopatterns with difunctional nanophase A and C. And the site-recognizable properties and mechanisms of the difunctional nanosites to different metal and metal oxide nanoparticles will be investigated. With the difunctional periodic nanopatterns as templates, both the nanopatterns and positions of the metal or metal oxide nanoparticles on the templates can be accurately controlled by adsorption or bonding due to these two kinds of the site-recognizable nanosites. Finally, two kinds of ordered nanoparticle/nanowire arrays of metal/metal oxide with controlled position and size on one substrate can be fabricated by in-situ transfer to silicon substrate by using the oxygen plasma method or two-step calcination method. A novel approach for fabricating multifunctional nanodevics, such as optoelectronic/semiconductive, optoelectronic/magnetic, can be available by the harvest obtained from this project.
