Single Electron Transistors

In this work an introduction is presented the two subjects of recent research in the nanotecnologia area. One is about Nanotubos de Carbono and Single Electron Transistors. The text has level of scientific spreading. Some characteristics make with that the carbon is a chemical element of great importance, over all for the construction of devices, between which, valley to detach: Participa of the composition of 16 composite million; the sixth more abundant element in the universe; not magnetic Not-Metallic and; electronic Configuration: 1s2 2s2 2p2; Different types of hibridizao; Traditionally, the known allotropic forms more are the graphite and diamente. However, in the passed century, the carbon if became one of great objects of basic and applied research. It enters the main discoveries in the area, is distinguished white carbon or ' ' ceraphite' ' in 1969, the fulerenos in 1985 and the nanotubos of carbon in 1991.
