Photodetectors which convert an incoming light signal to electric current or voltage are needed for an extremely diverse range of technologies from optical communication and environmental sensing to process control and materials characterization. One key performance metric for photodetectors is the spectral range of light that can be sensed. Broadband detectors that work over a wide range are more useful universally as different applications operate in different parts of the light spectrum. Other high-performance metrics include fast response speed, high detectivity for sensing of low light levels, room temperature operability which forgoes the need for cryogenic cooling, and device miniaturizability to allow for scalable production.The researchers have designed a novel photodetector heterostructure incorporating four different two-dimensional (2D) materials that is sensitive to light across a decade in energy from the mid infrared (IR) to deep ultraviolet (UV), or 0.3 to 5.0 eV, at room temperature. The peak specific detectivity reaches 3.4x10^9 Jones and the electrical bandwidth is 2.2 MHz, the fastest yet reported for detectors with deep UV to mid IR sensitivity. Finally, the active area can be made smaller than one square micron while unaffecting the broadband spectral response. This high-performance photodetector thus can be used ubiquitously across many different applications. For this technology, a provisional US patent application was filed on Nov. 17, 2021, and a paper was published on Apr. 11, 2022 (Nano Lett. 2022, 22, 8, 3425-3432).

将入射光信号转换为电流或电压的光电探测器需要用于从光通信和环境传感到过程控制和材料表征的各种技术。 光电探测器的一个关键性能指标是可以感测的光的光谱范围。工作在宽范围内的宽带探测器更普遍地有用，因为不同的应用在光谱的不同部分中操作。其他高性能指标包括快速响应速度、用于感测低光水平的高检测率、无需低温冷却的室温可操作性，研究人员设计了一种新型光电探测器异质结构，该异质结构包含四种不同的二维（2D）材料，该材料对中红外（IR）至深紫外（UV），或0.3至5.0 eV。峰值比探测率达到3.4x10^9琼斯，电带宽为2.2 MHz，是目前报道的深紫外到中红外灵敏度探测器中最快的。最后，可以使有源区小于一平方微米，同时不影响宽带光谱响应。因此，这种高性能光电探测器可以在许多不同的应用中广泛使用。该技术于2021年11月17日提交了临时美国专利申请，并于2022年4月11日发表了一篇论文（Nano Lett. 2022，22，8，3425-3432）。
