UCLA Physicists Create World's Smallest Incandescent Lamp
May 6, 2009
University of California, Los Angeles physicists have created the world's smallest incandescent lamp using a filament made from a single carbon nanotube only 100 atoms wide. Invisible to the untrained eye, the filament appears as a tiny point of light when the lamp is turned on. Even with the best optical microscope it is only just possible to resolve the nanotube's non-zero length. The team uses an electron microscope capable of atomic resolution to image the filament's true structure.
