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自由度的旋转/轨道自由度的影响，并在钙钛矿自旋装置中实现有效的自旋注射和运输。卤化物钙钛矿是光伏领域中的快速升起的恒星，具有独特的优点，包括低成本加工，良好的电荷传输和高光吸收。但是，关于它们的物理特性有一些疑问。该项目将探讨分层钙钛矿和无铅混合化合物的合成和表征，并使用这些新材料电荷/自旋传输设备。由于钙钛矿半导体的强电荷旋转 - 轨道相关性，该项目不仅对基于旋转的设备，而且对基于电荷的能量转换和与Halide Perovskites相关的存储应用产生重大影响。
