Radical materials and devices for opto-spintronics

在这个项目中，有机自由基材料的基本光和自旋物理学将研究分子尺度电子学和量子信息技术。与大多数含有全对电子的有机材料不同，自由基的未成对电子具有一种称为自旋的量子力学性质，这种性质产生了磁性和“双重态”特征。我们已经证明，它们的自旋特性可以与强发光相结合，制造出高效的有机发光二极管，用于将电转换为光：比迄今为止使用的非自由基对偶更有效。通过利用自由基的发光、自旋和磁性，学生将探索光电子和自旋电子结合应用的新功能，朝着光自旋电子学的方向发展。

In this project, the fundamental photo- and spin physics of organic radical materials will be investigated towards molecular-scale electronics and quantum information technologies. Unlike most organic materials which contain all-paired electrons, the radicals' unpaired electron has a quantum mechanical property called spin which gives rise to magnetism and 'doublet' character. We have shown that their spin property can be combined with strong luminescence to make highly efficient organic light-emitting diodes for converting electricity to light: more efficient than non-radical counterparts that have been used to date. By utilising the radicals' luminescence, spin and magnetic properties, the student will explore novel functionality for combined optoelectronic and spintronic applications, towards opto-spintronics.
