Researchers build IR light detector with nanotubes

The device, known as an IR bolometer, is made by suspending a 0.5mm wide film of single-walled carbon nanotubes (SWNTs) over a 3.5mm gap between two electrical contacts. The film is heated by incident IR radiation, causing its resistance to change.
