Millimeter-wave detection and imaging is a rapidly developing field with both commercial and national security applications. This research is focused on the design and demonstration of high performance backward diode detectors and imaging arrays. The heterostructure backwards diode has been shown to outperform existing detectors at room temperature. The devices are promising for applications in security, avionics and signal detection, where they can image through smoke, haze, and opaque materials such as fabric for remote chemical and explosion detection. In addition to imaging, the sensors are part of systems for electronic data collection, in detection, categorization and analysis of signals. The detectors do not require cooling to obtain major sensitivity enhancements, which reduces cost and increases efficiency. Improvements in detectors and arrays come through an interdisciplinary program of device design and numerical simulation, coupled with fabrication and measurement-based models for the devices. The project engages undergraduate and graduate students and will generate a series of case students for curricular enrichment. The continued development of semiconductor materials for electronic applications benefits a broad spectrum of disciplines and applications. Spin-off applications of this sensor technology include communication, high-performance wireless networking, medical imaging, astronomy and general metrology.

毫米波探测和成像是一个快速发展的领域，具有商业和国家安全应用。 本研究的重点是高性能后向二极管探测器和成像阵列的设计和演示。 异质结构反向二极管已被证明在室温下优于现有的检测器。 这些设备在安全，航空电子和信号检测方面的应用前景广阔，它们可以通过烟雾，烟雾和不透明材料（如织物）进行远程化学和爆炸检测。 除了成像，传感器是电子数据收集系统的一部分，用于信号的检测，分类和分析。 探测器不需要冷却来获得主要的灵敏度增强，这降低了成本并提高了效率。 探测器和阵列的改进是通过设备设计和数值模拟的跨学科计划，再加上设备的制造和基于测量的模型。 该项目吸引了本科生和研究生，并将产生一系列案例学生，以丰富课程。 用于电子应用的半导体材料的持续发展使广泛的学科和应用受益。 这种传感器技术的衍生应用包括通信、高性能无线网络、医学成像、天文学和通用计量学。
