An optical/electric dual-mode photodetector array for human–machine collaborative infrared imaging was demonstrated. The responsivity of the photothermoelectric photodetector was improved by the ...
A single topological insulator photodetector covers visible through terahertz light at room temperature, combining two ...
(Nanowerk News) In general, most of the objects we use in our everyday life emit light in a range of the spectrum that is invisible to the naked eye. Typically, for those room-temperature objects, ...
The new long-wavelength infrared photodetector could be used in night vision, optical communication, and thermal and medical imaging. Northwestern University researchers have developed a new approach ...
