News From the Field
UCLA Physicists Create World's Smallest Incandescent Lamp

May 6, 2009

world's smallest light blub 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. Full Story
