  1. 1. Graphene FET terahertz detectors on flexible substrates

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Xinxin Yang; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensors; THz detectors; flexible electronics; 2D materials; Graphene; field-effect transistors; plastic substrates.;

    Abstract : Terahertz (THz) science and technology have developed rapidly over the past decades, extending the THz application areas from spectroscopy and earth and space sciences to communications, biomedicine and security sensing. Many of these emerging applications require shape-conforming, light-weight and low-cost detectors rather than existing solid-state detection technology. READ MORE
