This project aims to demonstrate room temperature hybrid nanowire-nanoantenna infrared photodetectors by integrating plasmonic nanoantennas on semiconductor nanowire arrays. It is expected that such novel device architectures will not only bring enhanced performance in responsivity, detectivity, and photoresponse bandwidth, but also additional functionalities such as selective wavelength and tunable polarisation, which may significantly outperform current infrared technology. The outcomes will provide a new device platform for next-generation, large-scale, reduced-cost, high-performance imaging systems in self-driving navigation, object identification, spectroscopy, and other high-end defence and civilian applications.

该项目旨在通过在半导体纳米线阵列上集成等离子体纳米天线来演示室温混合纳米线-纳米天线红外光电探测器。预计这种新颖的器件架构不仅会提高响应率、探测率和光响应带宽的性能，而且还会带来选择性波长和可调谐偏振等附加功能，这些功能可能会显着优于当前的红外技术。研究成果将为自动驾驶导航、物体识别、光谱学以及其他高端国防和民用应用中的下一代大规模、低成本、高性能成像系统提供新的设备平台。
