Abstract

Abstract: Various applications of terahertz (THz) radiation and the importance to fundamental science make the development of THz technology one of the key areas in modern applied physics. THz detectors are a key component of THz technology, whose performance determines the application market. One feasible approach to fabricate high performance THz detectors is to utilize carbon nanomaterials, particularly, carbon nanotubes (CNTs), and graphene. Their novel thermal, optical, and electronic properties make them promising in the field of THz technology. In this review, based on a brief introduction of the unique properties of graphene and CNTs, the fundamental principles of thermal, electronic, and photonic effects in carbon‐based THz detection are thoroughly discussed, together with the detailed summary of major progresses in the past decades. Finally, the challenges and opportunity of such THz detectors are presented from three aspects of precise preparation of carbon nanomaterials, mechanism of THz detectors and device technology. Abstract : Carbon nanotubes and graphene have unique structures and properties, specifically the unusual thermal, electronic, and photonic effects, which make them highly promising for high performance terahertz detectors. This review covers the major advances in terahertz detectors based on carbon nanotubes and graphene, mainly including the structure characteristic and fundamental principle, as well as the challenges and outlook.
