Filling this gap, researchers at the Peking University School of Electronics and collaborators ... indicates that the HGFET can detect weak infrared radiation at 0.46 nW cm −2 levels, thus ...

(Passive InfraRed sensor) A device used to detect motion by receiving infrared radiation. When a person walks past the sensor, it detects a rapid change of infrared energy and sends a signal.

It’s called absolute zero. Any object with a temperature above this will emit and absorb infrared radiation, even the Earth. Speaker two That’s right, and the rate at which infrared radiation ...

Technology has now moved on, and it is now possible to generate continuous-wave terahertz radiation by exposing a semiconductor to beams from two infrared laser diodes that are very close in ...

Terahertz electromagnetic waves occupy a middle ground between electronics waves, like microwave and radio waves, and photonics waves, such as infrared and UV waves. For example, mobile phones use ...
