Two-Dimensional Material Tandem Detectors for Polarimetry and Spectroscopy

该项目的目的是利用二维（2D）材料为垂直堆叠（串联）光电探测器提供的基本优势。许多二维材料所表现出的强吸收、可调带隙和偏振依赖性，为探测光的特性提供了一种手段。该课题具有重要意义，因为它可以克服当前串联探测器的成本/性能问题，从而实现广泛使用。预期的项目成果是开发一种新型串联二维探测器，它作为单个探测器/像素，可以提取入射光的强度，偏振和波长区域。这将为未来的许多应用带来好处，包括机器视觉和航空测量。

The aim of this project is to leverage the fundamental advantages that two-dimensional (2D) materials could provide to vertically-stacked (tandem) photodetectors. The strong absorption, tunable bandgap and polarisation dependence that many 2D materials exhibit, provides a means by which to detect properties of light. This topic is significant because it could overcome current cost/performance issues of tandem detectors, enabling widespread usage. The expected project outcome is the development of a novel tandem 2D detector, which as a single detector/pixel, can extract the intensity, polarisation and wavelength region of incoming light. This would provide benefits for many future applications, including machine vision and aerial surveying.
