摘要

半导体材料正在成为实验和理论研究的中心课题，使其能够克服大多数材料对亚太赫兹辐射响应差的技术挑战。由于半导体晶圆电导率的变化，可以通过光照射有效地调节其亚太赫兹传输。本文研究了n掺杂硅片的光导效应及其对亚太赫兹电磁波传输能力的影响。实验研究了130 GHz电磁辐射传输随光照的变化规律。分析了照明、光致电导率和亚太赫兹传输之间的关系，提出了用于太赫兹应用的光控器件的概念。

Photo-induced switching for sub-terahertz applications

Semiconductor materials are becoming a central topic of experimental and theoretical research, enabling to overcome the technological challenges of poor response to sub-terahertz radiation that characterize most materials. The sub-terahertz transmission of semiconductor wafers can be effectively tuned by light irradiation due to the changes in their conductivity. This paper investigates the photoconductivity effect in n-doped silicon wafers and its influence on the transmission ability of electromagnetic waves in the sub-terahertz frequency range. The changes of the transmission of 130 GHz electromagnetic radiation as a function of illumination are experimentally investigated. The correlation between illumination, photoinduced conductivity and sub-terahertz transmission is analysed, proposing the concept of an optically controlled device for terahertz applications.

期刊介绍： Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials. OPTICAL MATERIALS focuses on: • Optical Properties of Material Systems; • The Materials Aspects of Optical Phenomena; • The Materials Aspects of Devices and Applications. Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
