项目摘要

This project is at the interface between colloid chemistry and electronic engineering. It is aimed at the development of novel devices for optoelectronic applications. The devices are based on colloidal suspensions of electrically polarised particles, which perform similarly to liquid-crystalline materials. Suspended semiconductor nanoparticles and heterostructures will be used for control of electronic and optical properties of the systems. We are aiming to combine two novel ides and approaches: (i) a chemical approach to create a fabrication method for nanoparticles of permanent electric dipolar moment based on freezing the polarisation of microemulsion drops, which produces colloidal liquid crystals , and (ii) an engineering approach to develop novel Suspended Semiconductor Particle Devices for light control based on semiconductor nanocrystals and heterostructures. We will develop these ideas to produce colloid liquid crystals based on semiconductor materials. This would allow us to use weak electric fields to control the optical and electronic properties of thin films of suspended semiconductor particles. The successful combination of these new ideas would provide a route to fabrication of completely novel devices for light control with a number of optoelectronic applications, like large TV displays, electronic paper, sky roofs and smart windows.

该项目处于胶体化学和电子工程之间的交叉点。它的目的是开发用于光电应用的新型器件。该装置基于电极化粒子的胶体悬浮液，其性能与液晶材料类似。悬浮的半导体纳米粒子和异质结构将用于控制系统的电子和光学特性。我们的目标是结合两种新颖的想法和方法：（i）化学方法，基于冻结微乳液滴的极化，产生胶体液晶，创建永久电偶极矩纳米粒子的制造方法；（ii）工程方法，开发基于半导体纳米晶体和异质结构的用于光控制的新型悬浮半导体粒子器件。我们将开发这些想法来生产基于半导体材料的胶体液晶。这将使我们能够使用弱电场来控制悬浮半导体颗粒薄膜的光学和电子特性。这些新想法的成功结合将为制造全新的光控制设备提供一条途径，该设备可用于多种光电应用，如大型电视显示器、电子纸、天窗和智能窗户。
