Abstract

Ultrasensitive Self-Driven Terahertz Photodetectors The combination of new topological materials and terahertz (THz) technology shows that micro-nano quantum structure is very dynamic in the detection of complex feature information of photoelectric detection system, and opens up a new technical path in the field of THz safety detection and medical imaging. Explicitly, the unique electronic properties of NiTeSe with type-II Dirac-cone electrons just located in the nearness of the Fermi level enable the fabrication of ultrasensitive antenna-coupled THz photodetectors. More details can be found in article number 2205329 by Huaizhong Xing, Yulu Chen, Antonio Politano, Lin Wang, and co-workers.
