The terahertz (THz) region of the electromagnetic spectrum, broadly defined as between 300 GHz and 30 THz, is of growing importance in fields as diverse as communications, medicine, astronomy, security, biology and materials science. Despite this, the technologies for detection of THz radiation are still comparatively immature. The most sensitive THz detectors are typically slow and require cryogenic cooling, and conversely the fastest detectors lack the sensitivity to measure weak signals. We describe here recent work to employ new two-dimensional (2D) materials for the detection of THz waves.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
