Progress in performance development of room temperature direct terahertz detectors

Abstract In this paper issues, associated with the development of THz direct detectors and focal plane arrays in last decade are discussed. After short description general classification detectors, more details concern Schottky barrier diodes, CMOS-based microbolometers, field-effect transistor where links between devices modern technologies such as micromachining underlined. Special attention has been paid to made two-dimensional materials. Their performance is comparable that presented for classical terahertz detectors. It shown applications nanoscale materials devices, particular, materials, open door further improvement operated at room temperature.
