项目摘要
9412931 Crowe These diodes are now in use around the world for a variety of scientific applications, including, radio astronomy, plasma diagnostics, chemical spectroscopy, atmospheric chemistry, and compact range radar measurements. Previous research has led to the creation of devices that have record performance at frequencies from 1-5 THz. These studies have also indicated that further performance improvements and increased operating frequency are possible. Three graduate students will be involved in this research, two of which will be supported by this grant. Together these students will form a team that strives to fully understand the physics of operation, design and fabrication, and testing and evaluation of THz Schottky diodes. The second technological goal is the research of a novel varactor diode based on a Schottky contact to a two-dimensional electron gas and its use as a millimeter and submillimeter wavelength multiplier. This inherently planar device technology has already demonstrated comparable performance to state-of-the-art planar Schottky devices. Through this research, these novel varactor diodes will be shown to have superior performance to standard Schottky varactors and will thereby become an important source of millimeter and submillimeter wavelength power. ***
9412931 Crowe这些二极管现在在世界各地用于各种科学应用,包括射电天文学,等离子体诊断,化学光谱学,大气化学和紧凑型雷达测量。 以前的研究已经导致创建了在1-5 THz频率下具有创纪录性能的设备。 这些研究还表明,进一步的性能改进和提高工作频率是可能的。 三名研究生将参与这项研究,其中两名将得到这笔赠款的支持。这些学生将共同组成一个团队,努力全面了解THz肖特基二极管的操作,设计和制造,以及测试和评估的物理学。 第二个技术目标是研究一种新型的变容二极管,这种二极管基于与二维电子气的肖特基接触,并将其用作毫米和亚毫米波长倍增器。 这种固有的平面器件技术已经证明了与最先进的平面肖特基器件相当的性能。 通过这项研究,这些新的变容二极管将被证明具有上级性能标准肖特基变容二极管,从而成为一个重要的毫米和亚毫米波长的电源。 ***
