Hybrid nanowire-nanoantenna infrared photodetectors

本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展示室温复合纳米线-纳米天线红外探测器。预计这种新颖的器件结构不仅将在响应率、探测率和光响应带宽方面带来更好的性能，而且还将带来额外的功能，如选择性波长和可调偏振，其性能可能显著超过当前的红外线技术。这些成果将为自动驾驶导航、物体识别、光谱和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。

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.
