This project aims to investigate the impacts of spin/orbital degrees of freedom of electrons in perovskites, and to realise efficient spin injection and transport in perovskite spintronic devices. Halide perovskite is a fast-rising star in the photovoltaic field and possess unique merits including low-cost processing, good charge transport and high light absorption. However there are questions regarding their physical properties. This project will explore the synthesis and characterisation of layered perovskites and lead-free hybrid compounds, and use these new materials in charge/spin transport devices. As a result of the strong charge-spin-orbital correlation in perovskite semiconductors, the project is expected to have a significant impact on not only spin-based devices but also charge-based energy conversion and storage applications related to halide perovskites.

该项目旨在研究钙钛矿中电子的自旋/轨道自由度的影响，并在钙钛矿自旋电子器件中实现有效的自旋注入和输运。卤化物钙钛矿是光伏领域的一颗冉冉升起的星星，具有成本低、电荷传输好、光吸收高等优点。然而，关于它们的物理性质存在问题。该项目将探索层状钙钛矿和无铅混合化合物的合成和表征，并将这些新材料用于电荷/自旋传输器件。由于钙钛矿半导体中强的电荷-自旋-轨道相关性，该项目预计不仅对基于自旋的器件，而且对与卤化物钙钛矿相关的基于电荷的能量转换和存储应用产生重大影响。
