Hole Spintronics – making your spin last longer

大多数电子设备是由传统晶体管供电的，这些晶体管使用的是一项有50年历史的技术。基于自旋的电子学(自旋电子学)使用电子的自旋而不是它的电荷来存储、处理和传输信息。尽管芯片上一半的晶体管使用空穴，但几乎所有的研究都集中在电子上。然而，空穴具有与电子完全不同的自旋性质，并且被预测在自旋电子学方面具有显著的优势。该项目旨在开发制造基于空穴自旋的电子设备的新材料和技术，设计长寿命的空穴自旋态，并开发将为半导体行业未来的自旋电子器件奠定基础的知识。

Most electronic devices are powered by conventional transistors that use a 50-year-old technology. Spin-based electronics (spintronics) uses the electron’s spin instead of its charge to store, process and transfer information. Although half of all transistors on a chip use holes, almost all research has focused on electrons. However, holes have completely different spin properties than electrons, and are predicted to have significant advantages for spintronics. This project aims to develop new materials and techniques for making hole spin-based electronics, engineer long-lived hole spin states, and develop the knowledge that will underpin future spintronic devices for the semiconductor industry.
